@Tuckstir has a thread on setup/maintenace: https://community.guitartalk.co.za/d/26611-guitar-set-up-101/31
All good stuff, it's a real useful skill to know what bits are what and how to can tweak into a ideal setup.
Personally, I'd get my own beater to work on - Strats are the most moddable guitar (followed fairly closely by the tele - which is slightly simpler).
One of these is a good option: https://community.guitartalk.co.za/d/27092-revolution-partscaster-x2-r1000-ea
I'd go for the Samick - not free, but make a offer - you never know.
