Another good basic primer: http://www.liamrosen.com/fitness
If you're looking for a good solid strength program, buy Mark Rippetoe's Starting Strength and do the program.
A slightly more varied, and less hardcore program is in Schuler & Cosgrove's The New Rules of Lifting. I find the texts complementary. SS has the better (IMO) beginner's program, TNROL has more complete information on overall fitness and diet.
SS is also going to benefit more from access to a proper gym with power cages, chin bars, and bumper plates (ideally). TNROL can be done largely at home with fairly a bit of equipment.
Once you pick a program and start doing it, re-read the FAQs and basics, then post any specific questions you've got to a decent forum (/r/fitness is pretty good).
