what you need to bring depends of course on how the trip is set up - I'm reading your original post to mean that you are "coming along for the ride", rather than being a semi-independent trip participant.

if you are going with an experienced BWCA tripper, more likely than not, all that you will be asked to bring will be your own personal items, and will wind up packing along some of the "group" equipment.

if that is correct, then about all you might be bringing is the clothes you'll be wearing, raingear, a complete spare set of clothes including a pair of camp shoes, raingear, your own fishing gear, and most likely a good sleeping bag and sleeping pad; and "personal" stuff such as toothbrush, TP, bug dope, headnet, sucscreen, first aid kit, medication, spare glasses or contacts - anything you can't leave home without - and if any of that is essential (like you can't see at all without glasses), you must bring spares in case of loss or breakage.

"wetbooting", more commonly called "wetfooting" means that you will be stepping in the water to enter and exit the canoe as it floats near the landings - noone wants to trash tthier expensive kevlar canoe by dragging it on shore and getting out with dry feet.  often, the landing area at hte putin will not even offer a choice.

if you are expected to be semi-independent, then you'll need the whole "kit and kaboodle" (bring spare kaboodle) - break that down into the major "topics" -  - what do I need to bring to camp/sleep;  to cook and eat, to fish etc.

the gear lists are a big help as a starting point, and then refind from there

don't go undergunned in the sleeping bag or raingear area - those two tend to be the areas that can give you the most misery if you can't sleep warm enough or stay dry in cold windy conditions, and nobody is going to have spares for you to use.

search for and read the threads on here about packing, and take to heart the advise about keeping your sleeping bag and spare clothing dry by double or triple waterproofing your packs

there are a lot of other threads you can find with specifics on footwear and packs - unless your partner objects, any decent backpack will work if it is large enough for your gear - I'll recommend the OTB Abyss boots you'll find reference to, but there is a big variety of choices in any of those categories.  You might also watch the "classifieds" on here to see is anyone is selling a pack you might be interested in -  I recommend a pack that has a padded hipbelt and padded shoulder straps
