Access Point and Wireless Bridge?!

I am currently looking at getting my Xbox 360 back on-line and also my soon to be LG Blu ray player on-line as well. I already have excellent wireless reception in my room. Previously, i have run an Ethernet cable from my laptop to my Xbox, however, this was annoying as it was a 5 metre cable!

I have started looking into access points and wireless bridges, however, I am unsure on which one I need and how I would get it to work on my Cable wireless connection [ Belkin N1 Vision]

Basically, what I am asking, is which device would be best to get 2 devices on the wireless, and how would I configure it to do so, through the proected wi-fi.

Thanks
Oliver
