Welcome. There is a lot of information here to help you. For starters, I suggest doing some searches through the forum for paleo and zone (or Google
[w/fs] if you prefer). Also check out this
(w/fs) "New to the Forum" post. For Zone you may also want to buy Sears' book (Enter the Zone), and for Paleo check out this website
(w/fs). When looking at any thread on the board, check out the Similar Threads section at the bottom.
Once you have done some ground work on the basics, you can post your more detailed or nuanced questions here and will definitely get some interesting responses.
