hello hydra.
there are a couple of threads on this section of the forum dealing with what to bring. but i'll save *some* searching and give my suggestions here:
-tools: your tool kit that comes with the bike is great for small things. Really, if you are travelling in "civilized" areas (major towns every couple of hours) you won't need much more. I carry an extra set of wrenches and some sockets because sometimes you need to hold onto the nut and loosen the bolt of vice versa. I carry too many tools, but I don't give a ****. So, i basically have the tool kit that comes with the bike doubled, plus some extra sockets for wheel axle or the like.
-camping gear: i have an msr multi fuel stove, and the fuel bottle doubles as emergency gas for me. I have a super light 2-person tent that I carry. I have a fire starter (flint stick), lighter and matches. There's my sleeping bag, and sleeping pad, and a towel. Then there's basic toiletries (always have at least two rolls of toilet paper). I have a hatchet and buck knife.
Oh yeah, if you're camping at camp ground, make sure you have a wine bottle opener. you'd be so surprised how many people don't remember a bottle opener. it's a great way to make friends with that group of cuties and you're the only one in the entire campsite with a wine opener.

-spares: if you don't have shorty levers, and your bike falls over on the uneven ground (it's pretty easy when drunk/hung over) then the last thing you want is a broken clutch lever. So, I travel with a spare clutch and front brake lever.
I started a thread with some general touring tips and other people posted some fantastic stuff.
before leaving, it's a good idea to have a general maintenance done, make sure everything's okay.
take a look at mileage, be prepared to buy tyres along the way. i've had a major service done half way through one of my trips in calgary, and i've also found myself 2000kms from home looking at a rear tyre that has 500km of tread left TOPS.
(i find advrider has too many people. it's so hard to find what i'm looking for, and almost any thread gets burried immediately)
once you have a route set out, let us know. i'd be more than happy to point out places to see (ie, roads to ride) in British Columbia.
I'd also suggest reading some ride reports on this forum to see what other people encountered.
hope this helps!
(welcome to the wonderful world of motorcycle touring!)
have fun, and be sure to post lots of pics!!!
