I recently got a semi-complete Leica V35 for free, it seems to be missing the bulb and holder, along with the lens.

So, is this thing worth fixing (I understand that it's supposed to be quite good), and in what manner? Some sites seem to recommend getting the original lens so the AF will work (what is this and do I need it?), while others recommend a Nikkor instead. And how hard are the bulbs to get and where do I get them from?

Sorry for all these not so bright questions, but I'm a complete newbie when it comes to the whole printing part of darkroom work.
