DC2NET Links

Hi! I have two sites with URLS which redirect to the real sites:
www.texifornia.com for texifornia.windhavenweb.com
www.galesgiggles.com for galesgifts.windhavenweb.com/giggles.html

I am not trying to mask the real site or trick google–I just wanted a shorter URL for some of my existing pages (without having to move the actual location of the pages). I try to link to the actual pages when I can, but in places like forums where the code automatically changes URLs to links, I usually use the shorter redirected URLS. Both of those URLS used to have a pagerank of 2 or 3 and now have PR 0, and I’m wondering if I am being penalized by google for redirecting, and if there is something I can do about it?
