Here are a few links to some very thorough gear lists.

Tree-planter.com
Replant.ca
Nataram.com

All the above links are great resources for getting you prepared for planting. The Nata link includes some prices from last year to give you a ball park of what you can expect to pay for brand new gear. If cost is an issue for you I highly recommend getting used equipment. You can save a bunch of money and pain, as broken in gear is WAY more comfortable than shiny new gear.

Both Tree-planter.com and Replant.ca give a good background behind the reasoning for selecting certain types of gear over others.
