Your bow is going to get wet, so make sure to take care of it and wax it up when you get home. Accessories are what you need to worry about while hunting. A quality sight with protected fibers is most important on my list. I've had more fibers break than I can count. Next, is a good quiver that will actually hold your arrows when crawling through the thick stuff. My Tightspot quiver does a pretty good job at this, although I did lose one arrow this year. I'm sure there are others that work well, but most of the cheap stuff will let you down.
One last piece of advice is to always check your equipment after you take a hard fall, which you will. Two years ago I fell face first and landed hard on my bow. I did a quick check and everything looked fine. The next morning I had an elk coming in so I nocked an arrow. The elk never gave me a shot, which turned out to be a blessing because when I look at my arrow, it was just kind of dangling there, cracked right in the middle. I proceeded to check the rest of my arrows, and 3 of the 6 were broke.
