A question about oil painting?

I'm just starting out using canvas paper rather than real stretched canvasses which are more expensive. I've done a few pictures so far, most not very good but the latest one isn't bad (plenty room for improvement of course) and I'd like to keep it. I don't know anything about the keeping... show more I'm just starting out using canvas paper rather than real stretched canvasses which are more expensive.

I've done a few pictures so far, most not very good but the latest one isn't bad (plenty room for improvement of course) and I'd like to keep it. I don't know anything about the keeping quality of the canvas paper. If I mounted it on board and framed it how long is it likely to keep?

I put gesso on the canvas paper first (the pad didn't say whether it had any on or not so I thought I had better do so) so will that have preserved it to some degree?

I feel rather intimidated when I look at the big stretched canvas and very nervous about putting the first bit of paint on it. Is this usual - should I just grit my teeth and do it, do you think? Is it easy to cover up any mistakes I might make? I haven't done any covering up on the canvas paper, just kept them for a short time to remind me not to do it that way again.
