Hello Kim,
You might find the Ropes and Straps CDs helpful. Jumprope + TRX sounds like a pretty good plan to me, especially for Boxing.
I travelled through Estonia (a former part of the USSR and now an independent country) recently and had my first encounter with a kettlebell. If you are looking for a "kick butt" workout, Kettlebell-Swings should be a part of it.
I also recommend a visit to the NSCA homepage. The Tactical Strength and Conditioning section features various articles that might help you to design your own comprehensive, time-efficient and effective workouts. There is a Paradigm-Shift under way in the Strength and Conditioning World, away from endless mile-eating to short crisp workouts, and you should benefit from that newly emerging knowledge!
Enjoy,
Olaf
