A couple of things to consider.
1. Wooden rods can and do break. They look nice, but that's no help in the field! If you have a wood rod I'd recommnend upgrading to a delrin (spelling?) rod. Strong, flexible. Not sure what the t/c comes with.
2. The T/C manual on page 34 has a pretty good instruction on field cleaing. You could go with that with no problem, although they specifically mention black and Pyrodex and not 777. For 777, I just use pre-lubed "Wonder Lube" patches as follows in the filed about every other shot or three you must address the crud ring 777 can leave: Brush a few strokes and twist at the bottomm of barrel, WL cleaning patch, WL cleaning patch, and then a regular dry patch. Good to go. There are a gazillion ways but mine works, too. Clean it good at home.
3. I don't beileve you need to lube powerbelt bullets, but I've never shot them. I shoot round balls out of my Hawken and sabot/pistol bullets out of my in-line.
4. Don't forget a spare nipple and tools to replace it. Nipple pick, etc.
