Hmmm, if you ever feel up to it, CM7 can be loaded through clockworkmod, it's just that you'll have to go all the way back to stock via odin 1-click. Then you just download the CM7 full nightly, and it'll proceed pretty easily (At least in my case, YMMV!). I believe CM7 puts you on a new version of clockwork, 3.2.somethingorother, instead of 22.214.171.124.
I've used My Tracks to keep tabs on where I've been, Runkeeper for when I go for a jog, but mostly Pandora, Trillian, and a few games (PewPew2 being my current favorite). When I'm stuck on a flight I'll watch movies using Rockplayer because it supports .mkv files. I've gotten into the habit of ripping all my movies to a server I have at home, and I use freemake to shrink them down to phone size. Oh yeah, I also use Camera360 for picutes, mostly because the stock app on CM7 kinda blows, but it still lets you do HD video recording.
As far as the mounting goes, I'm still working on that. I ordered the SW-Motech GPS mount for the Triumph Tiger (I think, I'll have to check) as it's a direct fit for the 919, just pop a few bolts out of the handlebar clamps, and you're off to the races. It'll accept a huge variety of RAM mounts and such, I accidentally ordered the large SW-Motech GPS bag (swear I clicked on the small one!), so my phone is inside there since it's waterproof and the touchscreen is usable through the plastic. I also use it for the GPS, since it fits in there too. The big SW-Motech bag is way too huge, it covers up my turn indicators so I have to lean forward to see if I've cancelled the stupid things. I'm thinking about going to a click-in style mount for the phone and GPS, but I'm a little leery of buying something for this again as I seem to have horrible luck on the sizes of these things. I do like the idea of the bag, and it does work well at keeping water out, but it also keeps heat in. when my cappy gets too hot it stops charging, and when I have the gps going it gets pretty warm. other devices might not have the same problem.
For Power I have a line running from the battery up under the seat to a fuzeblock, with switched power running to a powerlet plug I mounted on the handlebars. I have to say I've been a little underwhelmed by my powerlet plug. I love the idea, but I dislike that my plug does not want to sit in the socket properly. I lose connection to the battery all the time and have to "jiggle" the stupid thing way too often. I may ask for an RMA or something for the socket.
If you guys want pictures of the SW-Motech mount with the bag on and the powerlet socket or fuzeblock, I can get some when I get home and post them up.
