I've just got myself a new, sealed box, Joggler from e-bay

I'm pleased to report that it just upgraded when plugged in to a wired connection (couldn't get the original firmware to connect to WPA2 WiFi) - it now has 8686.53 (boardrev:2). No problems like other folk have reported recently - phew!
I'm a late comer to this wonderful little device, and to be honest Squeezebox.
My immediate plan is to run Squeezeplay to control the Receiver part of a Duet, but I also like the idea of retiring the old sub-notebook that I'm running as my Squeezebox server and putting that on the Joggler too with a big USB drive (once I've found or fabricated a suitably discrete USB connector).
I've done lots of reading and appreciate that as a minimum I have to enable SSH, and maybe I should go the PnP route, or just put a different Linux build altogether on the Joggler...
I'm a bit impatient (why didn't I find Squeezebox and the Joggler YEARS ago?) so I'm asking if the experienced folk here can offer some advice on my best route?
Thanks
