IIRC Ray Mears' rig for jerky used the fire to create a flow of warm air rather than to smoke the meat. I'm sure that some of the smoke flavour would find it's way in, but it wouldn't be properly smoked.
Smoking is really easy and very safe as long as you follow a couple of basic rules (especially with cold smoking). I've been doing it for a number of years now and can throughly recommend it.
You have two basic types: Hot and cold smoking.
Hot smoking cooks the meat at the same time as it smokes. This is suitable for fish, meat and poultry.
Cold smoking does not cook the food and is suitable for cheese, bacon, ham and some kinds of fish. If you are going to consider cold smoking 'raw' meat you need to do a little more reading as you are creating an environment where some nasty bacteria can breed.
There's lots of designs for smokers, many of them are easy to make at home for not too much money (
'trash can' example -
slightly bizzare example -
a youtube link to a bloke who likes showing his body off, but makes a cheap and simple design smoker)
For recipe ideas I can suggest having a look
here (don't worry that they all talk about one model of smoker, the recipies are the same for whatever you use. Times will vary, but you get the hang of it quickly)
There's also some good recipes on the
River Cottage forum
To answer your question about wood - I'd steer clear of the ones you mention. My rule of thumb is that any fruit wood is good (apple and cherry are favourites), Alder is also good. Stonger wood such as oak, mesquite etc are OK, but you need to be smoking something that can stand the flavour. Oak smoked fish for example is something I would never do as you just won't taste the fish for the smoke. Particularly avoid anything like pine as the smoke imparts a strong and really nasty resiny taste.
Be prepared for your first attempt to be somewhere between pretty good and a total disaster! The second attempt is usually pretty close to perfect and it's plain sailing from there on in.

HTH!
