I would recommend reading
Chess for Dummies by James Eade
Complete Idiot's Guide to Chess by Patrick Wolff
I have read both books among other books.
Also check out Chess.com's Everything You need to Know About Chess series:

Play games with long time controls 15min minimum.
Other tips:
1) Every move you make must have a purpose
ex: Pawn to e4 or d4 tries to control the center squares
2) When you opponent threatens a piece see if you can
a) Capture the attacking piece
b) Block the attacking piece
c) Create a bigger threat
ex:Threaten the Queen or checkmate
Have fun above all.
Your rating will improve as your board and tactical vision improves.
I have looked at a couple of your games. It seems that you are hanging pieces that is leaving pieces that the opponent can take for free
Simple solution is to look at the whole board and see which piece(s) are under attack.
Watch out for knight forks. This is one of the hardest moves to see.
