I don't think the forum looks outdated at all, really. The first two points are ok, but there's no reason to remove functional stuff. I think moods are fun, even if they're kind of useless, they spice up the profiles a bit.
"Competitons" should definitely be removed since it's been years since anyone used it.
The search function could be hidden for regular users. You could say it advertises Tp, but it has greater success pissing people off, as it seems.
Also "Register" could be hidden for logged in users.
