Ok, I think I'm out of the woods!! I reverted to stock, and re-rooted using motocache's method all went very smoothly and I can now install apps again from the market as well as TiBu. Thanks for all your help, I kind of knew what I had to do but wasn't looking forward to having to do it. At this point it seems it was worth the hassle as it seems to have fixed the problem. Definitely have a better understanding of things now, so I'll call it a learning experience.
