I think the only things that would be off-limits for me would be my brain and the essential appearance of my face - I want to be me, and I want the people that care about me / that I care about to be able to see me as me.
Eyes - check, I wear glasses, so a nice pair of upgraded eyes would be awesome.
Ears - check, please, before I need the hearing aids that I can see inevitably coming, like with Dad and Grandma.
Legs, knees, and feet - double check. Mine SUCK. I mean they work, but they always hurt.
Heart - triple check. Mine is oversized. Probably from having to work extra hard because of...
Lungs - CHECK. I've been asthmatic since forever, had a collapsed lung when I was 3. Barring an accident or my old Mafia connections catching up to me

, my lungs are almost certainly what WILL kill me at some point.
"Equipment", as
HIjol put it - check. I don't feel any compelling need on this score, but as long as we're rebuilding me and we have the technology....
Oh, and the Internet: hook me up, as long as I can turn off the connection to sleep.
