Been out of the game for a while. Looking to update the Nook. Best recovery+Best ROM?

I lost my Nook Tablet for a while and just recently found it again. I'd like to update the recovery tool and put a new ROM on it so I'm looking for suggestions.

I had previously rooted it and installed ClockWorkMod and then it is running some version of an Android ROM. I'm looking to update the ROM to something newer so I can make use of new apps etc. Also I know newer ROMs need newer recovery tools to install. Is CWM still the go to for that?

Thanks for any help! :)
