Wireless network questions

[BeardedNinjaGuy]

Ok, I have a question as to the best way to link up the following set up..

I currently have a wireless network at home, I run my laptop (wireless), a PC (wired), as well as a 3rd PC in another room (USB Dongle), and an Xbox360 (XBox Wireless adapter kit). I still have 2 free ports on the back of my wireless router if that is important.

If I wanted to add the following to this set up, what would be best?

Oppo BD-83
Panasonic TCP54V10

If I had the ability to also get the XBox running off of something other than the Xbox wireless adapter that would be fine, but not a big deal.

I dont yet have the 2 new additions, but im looking into how to do it, and what it would run.

Any help would be great.
