PS - Pointing me to a good book would be much appreciated.....
A very good book in my opnion that has to do with position plays is
Small Stakes Hold'em: Winning big with expert play by Sklansky/Manson. This book address how to play from the small/big blind and all positions. It has a list hand's that you should only play from each position at the table.
One thing, this book is geared for limit play alothough you could use it in any game.
This is a very complex question as there are so many issues to deal with.
Has the pot been raised? If it has, How many players have called. What are the odds
your getting? How many limpers in the pot. if you are in the small blind. I tend toward calling most hands from the small blind in an unraised pot with 2-3 people in. If the BB is aggressive you need to reevluate your hands. If found some really good articles on blind play, I can't post them here but if you would like to pm me i could send them to you.
