Just bought a new 2010 7.7 FX - need help accessorizing it (quality, price doesn't really matter much).

1. Want a comfy seat but still look sleak with this bike. I've read from here that the Fly Tri Gel Saddle by Terry is nice?
2. Wireless computer. Should I get a Bontrager Computer because there is an area in the fork to hook it up?
3. Combo pedal, because, sometimes I'll ride in areas with a lot of stop signs and lights, so I'd like to stay with a platform for that. But I want the ability to clip in when I can get out on the open road, or paved trails. Any suggestions? Not afraid to pay for quality.
4. 2 bottle cages. I bought the Bontrager Race Lite Cage for my down tube. I want another cage for my seat tube. From what I can tell, I don't think the Bontrager Race Lite Cage will fit on the seat tube with a cage on the down tube. My bike is 22.5 frame. Has anyone tried using 2 bike cages on this bike? What fits?

Thank You
