Welcome
The manual will tell them how much oil to put in. If you don't think they can manage that, don't go there :s
You shouldn't have to get your brake pads/rotors replaced for a sticker, but if they are worn then it's a good idea. If you want to do it yourself, it's not hard to change rotors and pads. There is a service manual available here for VIPs with instructions and just ask if you need more help. Ps Brakes direct is a great place to get your pads and rotors.
The lights are held together with glue. If it's just the glue cracked, you might be able to heat them up to melt the glue and reseal them. Just a thought, never done it...
Dyno tunes from physical shops are easy and probably pretty safe, but they are not cheap, aren't very flexible if you make changes, and you won't necessarily get an MPS expert tuning your car. You pay for a software licence and get a tune that is locked to your car and that shop.
Think of the AP (or Versatune) as a tool to load tunes, rather than a tune itself (yes it comes with OTS tunes, but they aren't great). They let you load tunes from a variety of tuners and aren't locked to one shop. You can also sell the device later on.
If you go down that route, you can get good OTS+ tunes (c. $100 I think) from stratified, freektune etc which will be ideal for stock/mild mods. If you want to mod then a full tune from strat/freek/rayd/others (couple of hundred $) etc can be loaded later using the AP.
If you think you might want to mod in future, that would be the pick. You can probably find a V2 for a lot less $ if you don't need gauges. If you don't want to mod much, maybe even a hypertech would be a cheaper option and you can also sell that if you ever want to mod more.
