Generally, if you can trim the main, you can trim the jib, the in-out sheeting angles are more or less in synch. Assuming the jibsheet leads are in the right place, just bring it in for close-hauled work until you can't pull it in any more without turning a curved sail into a too-flat and strangled-looking one. It's hard to describe how far in is "too far", you just get to recognize it from experience. Racers sometimes mark the sheets with magic marker to line up with a point on deck. You can carry the jib flatter in a stronger breeze, and ease it out a bit for a deeper curve shape in lighter air or choppier seas. The telltales along the luff of the sail will assist you.
Other than close-hauled, it's like the main, you ease it til it just starts luffing, then trim it just enough to put the luff back to sleep. On a broad reach to a run, it'll start to get blanketed by the main and look limp and useless. This isn't your fault, and you don't need to keep letting it out.
On a dead run, you can wing it out to windward, but you might want to save wing-and-wing and dead-running til you have a bit more experience, especially if you're singlehanding, since you're constantly on the edge of a jibe if you bear off a little too much.
Hope this helps with what I think was your question.
