1) The COLORS! - Jay i'm not sure if you plan on tweaking the colors of the layout but I think a "Black" background would look Much better instead of the grey... I know it would really make this new site layout look much better than all the different Grey's over each other.
2) Trader Ratings! - I know you mentioned this before and the bloat the old one caused, but it was a nice feature for people buying parts because it gave them something to view before purchasing so they didn't get ripped off.. Hope you can find a newer version that is much easier that causes less bloat on the system so members can have a piece of security when buying parts again.
Other than those things It looks great! I say try the Black background for a day and see what everyone thinks, if they like it, leave it...
Below the First image is the version as it is right now, and the Second image is how it would look in Black...
