I always throw in a can of mosquito repellent. The 40% DEET kind. I'm allergic to mosquitoes, so they really bug me. (sorry for the pun). As a bonus, I found that it keeps the other little critters away, even the bees.
If I'm running the splitter, chipper, or just using the axe I'll put on the worktunes earmuffs. Running the saw, though, I don't have them turned on normally, unless I'm just bucking up some little stuff.
The cloth gloves that have the blue rubber over them work very well when using the chainsaw, but keep them away from gas as it will eat through them quick. After a day's work, throw them in the wash with the jeans and they come out nice and clean.
Bucking to length for firewood, use the Mingo Marker. Best method I've used thus far, and I've used a lot of them.
I've got a little lawn tractor I drive up into the woods and use it to haul firewood, especially if I'm using the bigger tractor to move the chipper around. For better traction, I had the rear tires filled with Rimguard. Cost was about $30 at the American Tire Factory. HUGE increase in traction. I also have chains, but rarely have to use those.
