OK, check out BWCA.com and do some searching around you'll have more info then you know what to do with.
The best camp sites IMO are usually on points or islands the wind does a good job of keeping the other Mn state bird away. Also helps to spray your clothes down with permanone, and yourself with Ultrathon.
If you are going to be doing a loop route over several days always leave early before the winds come up, it's much easier and you don't know if your intended camp site is open until you get to it so the earlier the better because if it's not open you have to keep going until you find one that is, which can be a serious bummer after a long day, especially if you have to keep movin on in the dark.
You must know how to use a map and compass. As mjhMN has stated Fisher and McKenzie maps are the ticket and it's nice to have both. I also use a GPS to mark my entry point, portages and campsites as I come to them also.
I like a can of Yard Guard by the USFS toilet back in the woods.
Hang anything to do with food or hygiene, and your tackle box or bag. I use dry bags and as long as your not packing fresh foods you'll be fine. Also if you do fish clean them away from your camp and dump the guts in the woods.
The only thing in my tent is sleeping gear, clothes, PFD/pillow, flashlights, weapons, and people.
We usually fish, so I keep my reels in my pack and poles in a cheap Flambeau container then bungee it to the canoe.
Canoe packs work best because they ride lower in the canoe, my partner started using a internal frame pack last year because there more comfortable on long portages. I see a lot of both but prefer a canoe pack myself.
One more thing, get into town the day before if you can and stay at a hotel or local camp ground, I have also heard some outfitters have bunk houses
Hope it helps.
