Your choice of color is a bit unusual
You might see about bringing some of the glare off the stark white of the forums with just a hint of color in it, maybe a FFFFF8 or something similar.
As far as modifications go, those are good choices, tho I would consider the "last reply by" and anchor hacks to round out member usability.
They don't take much time to add, are stable, and make a good bit of difference.
