What Aimless said!!! If you want specific recommendations, we need more details. Since you didn't provide details in your profile, we have no idea where you are doing most of your backpacking.

If you haven't already found them, there are lots of excellent articles on gear selection (including clothing) listed in the left-hand column of http://www.backpacking.net/, the home page of this site.

Mark Verber has already provided a link to his excellent website.
