totally confused

I am new to this site and have no idea how to properly use it

The forum is broken down in to different categories. Find the category for the info your looking for here http://www.forabodiesonly.com/mopar/

or use the search function here http://www.forabodiesonly.com/mopar/search.php?

not sure how to post a question and no idea how to zone in on any response.

Same way you posted this question. Just post in the appropriate category. If you post in the wrong spot, no problem. Someone will move it to the correct spot.

I also note that I am receiving lots of points or messages in my email and do not know how to stop those

You will not recieve any spam from this site. You will only recieve a monthly newsletter or email regarding Private messages or subscriptions to thread you have been active in.

Is there a manual on how to use this site?

No manual available but but theres a forum that should help here http://www.forabodiesonly.com/mopar/forumdisplay.php?f=11
