There are lots of nice eyepieces out there, depending on budget of course: and you can't really go wrong with the Televues, but they add up pretty quick!
A step down in price, but good quality are Baader Hyperions, Vixen LVW's, Williams SWA, Takahashi LE series (the Taks don't have the wide field of the others, but they are super sharp and high contrast).
With f10 optics you will find that even the cheaper eyepieces will do a great job, like the GSO/Bintel Superviews: might be worth checking them out (around $60-70 at Andrews)
I put the GSO 2" Qtz dielectric diagonal on my CPC800, and it transformed the star images: a great investment! (Bintel has simply re-branded the GSO ones.)

I would be thinking around 10-15mm for high power, 20-30mm for medium power and general purpose, and maybe 40mm for wider fields, lower power. A focal reducer would be a good add-on for visual use as well. The Celestron/Meade ones drop the optics to f6.3, which gives you a wider field as long as you get the 2" diagonal to minimise vignetting.

I'm not sure why you need the fancier finder-scope with a CPC telescope. The Telrad would be quite adequate, or just the stock finder, because you only need it to find a couple of stars for alignment at the start of your session, and the computer does the rest. I use the stock finder once at the start of the night, and only ever use it again if I accidentally kick the power cord out or something.

- and I agree with Colin: I wouldn't bother with another focuser until I was intending to use the scope for AP. There is a bit of image shift with the standard focuser, but not much (nowhere near as much as the Meades I have used) - and it is perfectly adequate for visual use.

Good luck, and all the best.
