PR0 (all white bar) can mean 2 things.
1. Not enough incomings links transferring PageRank that supports a PageRank of 1 (or higher), or
2. A Google penalty - usually indicates you are doing something wrong or linking to someone doing something wrong (spam tactics).
In many, many cases #1 is usually the case.
If you have had the white and then it reverted to grey then get another domian and start again as it is hard to recover from these.
I have heard that you can try robots.txt for a couple of months then take it away and you may be included in google again
Been looking at this for you a lot of the backlinks that i tracked seemed to be on sites which where giving alot of 404's.
But I one thing I did notice was your dmoz and google diretory listings had both gone due to a the reshuffle at dmoz i think that damaged the site more then anything but they should be back next month.
