blogging for Dummies

Seriously People I.NEED.HELP. I don't know what I am doing. I have tried to change the look of my blog to make it more me and ended up with two backgrounds on top of each other and finally had to strip it clear and put up a generic background. Its ok but its not me:( Any advice? I have read/listened to the tutorials but I really need the book Blogging for Dummies! Do they even write those anymore? Probably not most people aren't dummies anymore except me Queen of computer illiteracy!! I digress. I need help in the design department and on how to add more than just 5 pictures if need be. Some day I hope to get to the "collage" point but I will live with baby steps.
