tire pressures depend on what tires your using, it would be best to talk to a race tire vendor of that brand. Generally speaking track pressures will be a little lower than street pressures to provide more grip at the expense of tire life (free grip would just be way to easy wouldn't it? lol). Most likely the pressures you're running on the street will do fine for a first trackday though.
what tires are you using?
as for suspension you should ride with what you're used to and change if it becomes a problem
if the suspension starts acting funky talk an instructor or someone with a lot of experience to help you (a suspension tech is best if there is one at the track)
some tracks are smooth some are rough and some just have some odd things thrown in (jumping the curbing at Barber for example) so that can be an issue too

Thanks for the info Woody. I'm running the OEM Diablo Corsas...only have about 1800 miles on them and not squared off or anything. I'm not planning on running it really hard, so it should be good. How many pounds would you drop in pressure from normal street pressure?
As far as the suspension, I'll probably leave it as is. Got it set right where I want it after lots of adjusting since I got the bike several months ago. Not too sure of the tracks condition though.

I ran 30/30 on my pilot powers...but you can ask the tech guys that does the inspection at the track...
on suspension setups...I don't know about where you're at but here in California there's always someone at the track that does suspension setups all day...they usually charge $40-$50...I strongly recommend you do the setups by professionals...it makes a world of difference...

I wouldnt worry about bike setup for a try the track program. I went last month to a team promotion try the track and what we did was follow an instructor around the track for 6 laps. and thats IT.
The pace was relatively slow, I left my normal tire pressure which is 32 front 34 read and i was fine.
Remamber, try the track is usually follow the leader format and the pace is usually fairly slow.

In the try the track programs that I've seen... you'll never get anywhere near speed to feel any differences in supension and tire pressure changes. Leave everything as normal.

Isn't that kind of like saying you're only riding to the corner store, so you don't need your helmet?
I did the Try The Track program with TrackAddix at Gateway last year and we got up to speeds over 130. I would think anything you could do to improve your bike for those speeds would be worth it, especially if you aren't used to riding that fast.
Just my .02

wtf kind of comparison is that? he's asking if he should lower his tire pressure and mess with suspension adjustments to do a handfull of slow laps on the track... Street pressures and settings will be perfectly fine for that and it has absolutely nothing to do with what speed you get to on a straight... at all... seriously the two things have nothing to do with each other. First of all, the lower pressures allow tires to get more grip along with heating up more, but street tires don't need nearly as much heat as race tires and are more likely to fall apart if they get too hot
but the main point is, 6-10 laps and his first time on a track: Tire pressures and suspension settings won't be an issue...

There were only 2 riders on my Try the Track session... and the instructor encouraged me to pass on the straight because he could see I wanted to. I finally passed, but I passed late on the straight and came into the corner faster than I anticipated. Nothing happened and I'm sure it wasn't anywhere near too fast for an experienced track rider. But if I had done something stupid, I still could've been in trouble.
All I'm saying is I don't agree with telling people they won't need something just because they are only riding on the track for 20 minutes. You can crash in 2 minutes as easily as you could in several hours.
Maybe I'm over reacting. I mean I agree you don't need to go out and buy all new race suspension, etc. but setting your tire pressures a little bit lower and adjusting your stock suspension could only help.

actually they can hurt just as easily as they can help which is why most advise you to ride on what your comfortable with at first. a couple pounds lower in the tires are not going to save you from crashing, changing pressure doesn't magically turn street tires into race tires and if you do go fast enough, lower pressures can overheat street tires and they'll start falling apart on you (note: thats not going to make you faster)
any race tire vendor will tell you setting pressures is more about attaining a certain temperature than getting grip from the pressure and once more street tires are made to work at much lower temps than race tires so getting them as hot as possible, probably not gonna help anything.
Ask a tire vendor how the pro's set their tire pressures. They measure cold temps and hot temps of the tires and look for the pressure that gets them the right change in temp between the two so that the hot temp is the same every time the bike rolls on the track. They're using pressures to get the right temps because race tires are very temperature sensative (try using a high end DOT race tire when its cold SLIPPERY). Street tires aren't that picky
and as for suspension, if it works for you on the street, it won't cause any problems at your first trackday. If you've got it set for your weight then making changes without help from somebody that knows what they're doing can easily make things worse. Any suspension tech will tell you to run with the sag set and see how it feels before making changes and most likely if you've never been on the track and your only doing a few laps, your ability to give usefull feedback on what the bikes doing will be limited.
now if your sag isn't set, do that but don't change the settings past that just to do it

Tires falling apart will not make me faster??? WTF!!! I've been lied to!
