Well, you asked about some wired options, so here's my take on wireless mice and wired keyboards/mice.
BT Logitech that's the same as the MX510. Can't recall the model, it's at work atm. It's terrific. I love the shape. I love the number and location of the extra buttons. It works like a champ with the internal BT module in all the Macs I've tried it with.
OK, keyboards. Here's my grip about wireless keyboards to start... I can understand the wireless mouse, it's something moves and sometimes the wires can be in the way, etc. Keyboards, though, stay in one place (more or less) so I don't get the need for the wireless keyboard. All your doing is using up batteries, which can be a PITA when they die and you haven't got spares handy! I can, however, see the desire for wireless set with a laptop. Would be cool to set it down and have your "real" keyboard and mouse just start working. So, that said, here's some thoughts on wired keyboards.
The Apple regular keyboard is very nice. The quality is very high, and the USB hub is nice, even if it is only 1.1. Gripes: it's white, which while it looks cool and matches the iMac, it gets dirty and shows it. Also, I really wish they made an "ergonomic" Apple keyboard. I use one at work and typing on my Apple keyboard at home gives me cramps.
I ordered a MS USB "Natural" keyboard which will arrive tomorrow. Should be more comfortable, but I'm hoping I can remap (and possibly relabel) the keys to match the Apple layout - the volume/mute/eject controls, the clear/equal key on the keypad, and the cntl/option/command keys, of course. Until Apple makes a comfortable keyboard, though, it's gonna have to do!
