Hey, Xeney! Where have you been?
Park Tools - way to go. Their site has everything including a cool point and click bike diagram so you know what to buy. Also, recommended lists: Home Mechanic Tools
Yes, sometimes specific brands take specific tools (such as RaceFace and Campy) but Park will tell you what works. The basic tools are usually available at a decent LBS.
