Things to Look For?

Hey everyone, I'm in the process of selling my 2010 regular cab and going to an old school Toyota. I'm looking at the one in the attached ad:

In speaking with the owner yesterday, I have the following concerns:
- There is a 1/4" size rust spot in the drivers side fender. He is going to send me some close-up photos of it sometime today. Granted, this is a 21 year old truck so I'm not too concerned with this. My question is, will the rust just keep spreading, or is there a way to stop it from getting worse?
- He has a 3" body lift on it and 31" tires. If I remember the model years correctly, this truck should still have a torsion bar suspension. 1) How hard is it to remove a body lift? 2) Can the torsion bars be cranked up high enough to fit 31's (or preferrably 33's) without the body lift?

Thanks everyone! Hopefully I'll be posting some pics up here soon!
