On road tyres I have always aimed to be at the normal road pressures but when the tyre is hot. For example, do your first gentle warmup session, come in to the pits and your tyres will have ballooned into the 40's. Drop them down to say 36psi all round. Check again after your next session and drop them to 36psi again. Next day when cold, you will have to put back a significant amount to raise them back up to 36psi
If you run road tyres too high they will balloon and wear out the centre of the tread, too low and they will flex on the rim wearing out your outer edge at an alarming rate [

Track tyres tend to run a little lower pressure as they have stiffer sidewalls and I always aim for 30-32psi when hot

The other thing that really wears tyres is corner entry understeer - scrubbing off the outer shoulders on the fronts. I used to do horrible damage to tyres on my first few trackdays
Try carrying a bit of braking into the turn, or if you don't fancy trail braking, just going in a bit slower []

]woodbridge is an excellent track day for the beginner. nothing to hit and far less intimidating than a circuit. snetterton is very fast for our cars standard. brands hatch indy is great fun also. trackdays with lots of 2nd and 3rd gear corners i would recommend to begin with and cadwell park should be on your list if your up the east side of the country. also for your first one i would suggest just changing the brakes to red stuff pads and see how you get on
yellow stuff -red just dissapear - seemed to last no time at all compared to green which I found ok on the road - or yellow which squeal until you get them really hot but last and dont create as much dust as red. However there are more expensive, more corrosive, more effective alternatives
I got a second set of wheels, then look out for 911/boxster owners who have a part worn set of track rubber. We have the advantage that a set of wheels and tyres will fit in the boot, so when the 911/boxster boys tyres are no longer road legal we can still use them and pick them up at a good price. The only downside to this is the fronts are often slightly narrow 205 instead of 225.
Agree with 944turbo as my red stuff brakes are crap when cold. they are good until the first track day event and then after this they seem to need warming up to the point where i have to drive every morning with my foot on the brake for about 200 yards otherwise they're dangerous. Should really start a thread on this but what do others recommend for normal driving 90% of the time but occasional heavy track day use (ie will last 20 min stints without fading)

Performance Friction PFC 97's - hugely superior to every other pad I've ever tried. (but £200+ for a set for late model turbo fronts). They last well, will actually outlast a set of discs (maybe that's because the discs wear quickly?)
Very corrosive on paintwork and wheels though. Work very well on the road also.
Peter Empson swears by Porterfields, and at a more reasonable price level, Mintex 1155's are a good pad - but nowhere near the PF's.
I'm afraid have nothing good to say about EBC. I'd sooner go with standard Porsche pads I think. The OP may be more limited in pad choice with the sliding calipers.
- on the tyres question, camskill are usually among the cheapest, but you do have to add on fitting charges. I bought some A048's last year and found one of my local tyre places to work out just as cheap ~ £70 / corner (OK, for 14" wheels [] )

The Pagids (yellow, blue, black, orange etc.) are very popular amongst racers but alas very expensive regardless of the size. The smaller size PFC's are dirt cheap compared to the late turbo ones. It seems PFC charge relative to the amount of material and Pagid just charge the same regardless.
This year I will be using Pagid yellows in the front (19's) with either blue or orange in the back.
