C-11 eyepiece & accessories?

What are good eyepiece choices for a C-11? I will be receiving a new C-11 sometime soon and am wondering about eyepieces. 1 1/4" or 2"? Radian or Nagler? Powermate or Barlow? Focuser? Any accessories I definitely need or definitely do not need? I will be doing mostly visual (especially DSO's), but I can see myself trying some imaging in the near future. I am really looking for some suggestions and advise.

Maybe I'm weird (OK, scratch the "maybe") but I find myself using my 17mm Nagler (165x w/.49 deg true field) or my 13mm Nagler (215x w/.38 deg TF) for 90% of my observing with the C-11. Except for planets these two are all I need. When I want higher power the 8mm Radian at 350x delivers. Occasionally I'll drop down to 103x (.66 deg TF)with a 27mm Panoptic, but really the 17mm Nagler is low enough power with the 11" - generally you go to lower power for wider field and increased light concentration but with the C-11 you already have plenty of light and the increase in true field isn't that much. To get a nearly 1 degree true field I can go with a 55mm Plossol but I very rarely do as I find the images with the 17mm Nagler much more pleasing. Only the 13mm Nagler can compare. Not that I'd toss a 31mm Nagler if I had one you understand -- I'm not THAT weird!
Maybe my preferences are influenced by having a Borg 100mm mounted piggy back on my C-11. The Borg with a 15mm Panoptic gives a 42x with 1.61 deg true field for wide angle views that the C-11 can't achieve.
