there are very few "easy jobs" on a sho. This statement is based on your apparent knowledge of how to use a wrench, not so much. I'm not trying to criticize or embarrass you i'm just saying to own and maintain a sho one should have a basic set of skills, or lots of money.
The shopheonix project site will tell and show you haw to do all these jobs, you should be able to determine if your up to these tasks. I suspect the amount of assistance one can expect around this forum is directly proportionate to how much you put into the understanding of the advice and your ability/courage to tackle these jobs. Again so you don't get your feelings hurt, this is just basic human/forum nature.
