Allow me to suggest you might want to pass by Barnes & Nobles and buy a text book or two, in order to familiarize yourself with all you'll need to do when you get back.
You should consider one or both of these: Barry Hampe, Making Documentary Films & Videos (my favorite) or Rabiger, Directing the Documentary. I'd also suggest one of these: Rice & McKernaan, Editing Digital Video or Button, Nonlinear Editing.
Second, if you do a quick Google Search you should be able to find a glossary of digital terms. Here I've done it for you.
I'm going to make a note that you should read now or before you start anything when you get back. This regards editing, but I'm writing it here because you have a tendency to do things first and then ask for advice: WRONG WAY!!!!
After shooting, to "capture" your video, i.e. to pass your video from tapes onto a hard disk drive, you can use any PAL miniDV camera or a SONY DSR deck (PAL/NTSC switchable).
Regardless of whether you'll be editing in PAL or NTSC, you'll need to purchase a hard disk drive (this is where you store all your video and it can be attached or removed to any computer laptop or table top, as well as to the computer that you'll be using to edit. This allows your editor to work on other projects and allows you to have "portability." Since external hard drives are so cheap, I'd suggest buying a 250 GB or 500 GB hard disk drive. Lacie is a good brand and these drives have always worked well for me. You could also look for a hard drive that has a ventilator. In any case, a top quality 500GB disk drive will cost you less than US$200,00. This is enough storage to store the edited version and all the media (the video and audio files that you have captured) of at least two documentaries.
One last suggestion: I always capture ALL the media in low resolution at first for the various edits (you will get slightly lower quality video and audio this way, but you'll save a lot of space on the hard disk) and re-capture the media (with Media Manager) at Standard or High Definition (whatever the maximum resolution level or your shooting material is, in your case, SD) only AFTER I've completed the final cut (and adjusted audio and video levels, added subtitles, graphics, etc.). This won't mean anything to you now, but your editor will understand.
Please note that the "logging phase" is associated witht the capture phase, in fact I (and many others) log and capture together, whereas others prefer to capture first and then log. "Logging" is the procedure whereby you list and describe every single shot on a tape. You want to make sure you use stars (for example) to mark your best video and you'll want to take care that you also note your best nat sound.
You will group similar shots in "bins." You can learn the basics of editing – i.e. the part YOU need to know, on a good text book and working with your editor.
Please note that this – LOGGING – is the most important phase – and the one that will determine the edit and the final outcome of your documentary. You must have the patience to log every shot correctly. This procedure allows you to see what (video, shots) you have available and to memorize your video (don't ask me how it happens because I don't know, but the logging process allows me to memorize, effortlessly, every single shot in 60 or more hours of video).
The logging process is something that you and your editor must do TOGETHER, so you both get to know all the video that is available. This allows you to map out your story and write an outline and will also allow you, during the edi,t to build sequences (because you know all the video that you have and where it is located).
It's easier than it sounds – and fun, at least for me – but make sure that you do some studying BEFORE you start any work when you return home otherwise you'll never be in control of what you're doing.
Also, Christopher has made a very good point. An editor is NOT to be considered like another piece of hardware. A good editor makes the difference, aside from the fact that he/she can save you non-withstanding mistakes you may have made. You should try to find someone who has edited one or more stories, similar to yours in a way that you like. Especially in your case where you know zip, a more-experienced editor will save your behind, teach you as you go along and make magic (if the material you've shot allows her/him to do so). I'm certain that you'll be able to get many suggestions regarding experienced editors from the members of D-word and/or asking for help from members of the IDA (International Documentary Association).
If anything, this is where you need to spend some extra money. A good editor is worth every cent and in your case they will also be acting as your producer, teacher, babysitter and fairy godmother. A top notch editor can make a great doc (if your material permits it) or at least save your butt and carve out something passable if you have the minimum required elements. Don't try to save the odd few bucks here because you'd be screwing yourself!
