Job search questions

So...I'm kind of in the job market and I'm not entirely certain how this all works. In the past, I generally was applying for part-time jobs, but this time I'm hoping for something that pays decently, etc.

First of all, any tips or advice anyone has for job hunting would be more than appreciated.

Second, and a bit more specific, I found a job that sounds pretty interesting. The thing is, it has a few things that are mentioned in the description but not really described (for instance, must be able to travel overseas without a description of why or or which countries). It's for a pretty big company and I actually think I'm qualified for it (WOO), which isn't something I come across very often as I've got a somewhat unhelpful educational background.

Is it best to apply for the job and then if there is interest shown I can ask questions concerning overseas travel (I don't mind, I'd just like to know where) during an interview? Or is this the kind of thing you're expected to contact in advance and ask about? From the description given it sounds potentially right up my alley.

Wow, thanks for the link! That sounds like exactly the kind of thing I need.

Yeah, I've looked into the website but they have a lot of different countries they work in. I actually think that they use the same description for a couple of different jobs, one of which makes sense to have overseas travel whereas the one I'm applying for I don't really get it. I'll toss them an email or try to call or something and see if I can find out some more information about it.
