(Hey Henry) I guess for starters, you want to be real confident with this job. If it doesn't come out to your liking, it may be a noticable thing. So, for 3/4" T&G flooring, you should be comfortable with a nailer for starters. And if you want to 'fix' an unsatisfactory installation, it will cost a lot of $$$.
Anyway, there are many sites out there to help familiarize you with this type of job. One, Popular Mechanics, gives a good layman's explanation. BUT, the real instructions should come with the flooring of your choice. (If not, ask for where to get them.) You ought to read the instructions FIRST because 1) you may not be able to rent the necessary tools if you need to rent them, and 2) you may get the feeling that you're in over your head. There are certain 'nacks' that come with this type of job. Which wall to start, and how to lay out the strips (for starters). Of course, preparation is key too because if it's not done per the mfgr's. specs., then you could void the warranty.
I'm not trying to discourage you from this type of job but you are doing the right thing by asking questions and reading up before you attempt this. There are other options out there. Engineered flooring can be an option for the Do-It-Yourselfer (DYIer). They can be stapled, nailed, and/or glued. If you go this route, look for a floor that can give you 2 or 3 sandings. (Do know that if you have a floor that can be refinished, it can only be refinished down to the tongue/groove, no matter if it's engineered or solid. Ask the retailer AND look at the thickness of the solid part of the strip / plank.) The more you shop, the more you'll learn. You should be conscious that you'll be raising the floor at least 3/4" from what's under the rug. You may raise it even more if you have to add any type of sub-floor or underlayment. This will play havoc with existing doors, thresholds, room transitions, and so on. Investigate this before you do too much.
