First Time DIY Service - 2004 "S" with 100k miles

[tconnarn]

Hello,

I have been reading many of the DIY posts here, and also on Pedro's Garage, and everyone here seems to be extremely helpful! I recently bought a used 2004 Boxster S, and it had 85k miles when i bought it, but the last service on record was the 100k. as i am now approaching the true 100k, i will be doing the 115k service myself, so that i can keep maintenance on this car as affordable as possible. It looks like i will primarily be replacing Oil, Oil Filter, Air Filter, and checking the fluids. I also plan to replace my spark plugs, and front brakes in the near future. Possibly the drive belt as well. I plan on lifting the car and supporting it on jack stands.

Has anyone had any surprises doing their own servicing, or and problems such as check engine light coming on after doing work? Do you have any tips or helpful hints to offer?

Will i need to purchase a diagnostic computer to reset anything after doing work?

Any info you can provide will be greatly appreciated! Thank you
