JoeGlo should work fine on removing all the old coffee oils. It basically a TSP (or similar) cleaner. I used Cafiza and it worked particularly well with hot, hot water.
There isn't much in the manual you'll need that you can't learn in 5 minutes on the machine or this forum.
If you are coming down to the Sunnyvale neighbor hood sometime, send me an email and I can show you my Elektra T1 and you can play around with it.
