Check out Mark Rippitoe's book Starting Strength, kindle version is $9.99. I think you'll find everything you want to know about technique, and getting strong. Also it includes a lot of information about woman, so it's not a "man centered" aplha-male bulkimizing weight lifting book. I would say read that, and get someone who isn't an idiot work your technique with you.
Lifting heavy(er) weights is very satisfying and nothing wrong with it, do it!
