Advise on fixing oil leaks this winter

[peregrinfalcon]

I have a small leak from the valve cover(cam cover) and also a small leak from behind the timing belt cover. I don't know what is leaking from behind the timing belt cover yet. My question is.....What would be leaking from behind the timing belt cover? There is 83000 miles on the car. The belts and waterpump were replaced at 66000. I know that the whole front of the engine has to be pulled apart to fix these leaks. What should I replace while I have it apart. Or, should I wait until scheduled belt/pump replacement to repair the leaks? I'll take it in to retension the belts this spring before I put it back on the road anyways. Any advice would be appreciated and will help me make my decsion.
