Hi,
In answer to your first question,I would go for the full JAR ppl because it took me 75 hours anyway to complete due to various reasons (ok..because I was crap!!) so the hours difference for me would have been pointless.
Secondly...you can get all the books you need from your flying club or school..and the equipment also...your new instructor will tell you what you need.
Enjoy yourself!
