Donna,
for you the ideal condition is to get a coach (or try some high-rated friends who can teach, and play unrated games with them - dont hesitate to ask questions in the chat). Second choice is - try online sites like http://www.chesstactics.org/ etc.
Not all books are good, and I have also bought many books but found only a few "digestable". The Opening books I mentioned are of the "easily digestable" variety.
Best of luck!
I got a tonne of books out of the local library covering a huge variety of things from tactics to openings etc and I just could not get the information into my head :(
