You can set up basic stuff, like keypad, display, jump, inputs, etc. beforehand, but for everything else you may want to wait until your 36XBR800 arrives so you can tell exactly what codes you need and where.
If you're eager, you can see what the 36XBR800 remote looks like
here.
I have a KF-60XBR800, which has almost identical functions, except I notice that the KV-36XBR800's remote has DRC MODE/PALETTE buttons not on my remote. I suspect that MODE changes between 480p/960i (which wouldn't apply to my set which is always at 768p) but PALETTE might be interesting. :-)
There's always a lot more codes for Sony TVs than merely what comes on the factory remote.
