This list will be revised several times prior to departure! Comments in red are my thoughts after being in Cameroon. As a general note, you need to bring enough stuff to deal with the first 3 months in training, before you get the hang of shopping in Cameroon. After that, you can buy most things you need here in country.
General Clothing
jeans (1) [Depending on where you live, this may or may not be necessary. They are very difficult to wash by hand.]
leather belt
socks (10)
rain jacket [essential for the rainy season!]
thin sweatshirt
jean jacket
swimming suit
Shoes
Casual Shoes(Teva Makayla)
Sports Sandal (Teva Omium) [not all the necessary. I only wore it once to go on a hike that nearly killed me. Not that useful if you aren't super sporty.]
Waterproof Sandal (Keen Bali)
Sandal (Teva Downtown OLA) [casual yet a bit dressy sandal like this was great. I wore this pair of shoes almost everyday for the first 8 months at post.]
Running Shoes
Personal Hygiene/Toiletry
Antibacterial Hand Sanitizer (one medium-size bottle)
Vitamin/herbal supplement
Body Wash (2)
Lotion (1)
Allergy Meds
Pain Killers
Cold/flu medicine
Tums/Chinese tummy meds
Prescription Eyeglasses (2) [PC advised against wearing contact lenses, but I ended up wearing it for most of two years. It wasn't a problem. Just be sure to bring a lot of contact solution!
Face lotion (1)
Leave-in Conditioner
Loofa (1)
Toothbrush (2)
Toothpaste (1)
Floss (3)
Hairbrush (1)
Tweezer, Razor/blades
Earplugs
Small hand towels
Travel Towels (2)
Office Supplies
notebooks (4)
Writing utensil

Kitchen Supplies
Plastic storage containers [possibly the best thing I brought with me. Pack your things in them. They are SO useful! tupperwear rock!]
Measuring cups and spoons
Ziploc style bags
Swiss army knife
Snack food
Small nonstick frying pan
Small cutting board
pairing knife
peeler
Light weight packaged food
Crystal Light/Propel packets
Electronics
iPod+travel speakers
Macbook [if you are bringing a computer, make sure you back up your files at home, and also bring an external hard drive - load that puppy up with movies, TV shows, language learning resources (French movies, etc) - be prepared for something bad to happen to your computer at some point during the service. the horrible electricity in Cameroon does damage. If you are buying a new one to bring, I recommend those cheap Netbooks.]
Cannon SD 450 Powershot + extra memory cards
Solio Classic hybrid solar charger [not necessary if short on money. but very useful as a backup battery, especially if you get posted somewhere power cuts a lot, or no power at all. - although I think for most PC countries/posts, this isn't necessary.]
Hand-Crank Emergency/Shortwave Radio [great for those quiet nights when the power goes out. I just got a cheap one and it picks up Radio France International and other local channels]
USB Flashdrive (2)
Power Adapter/Converter Kit
Luggages
Eagle Creek Grand Voyage 90L Travel Pack
Eddie Bauer Rolling Duffle
Moneybelt
Miscellaneous
Passport-size photos (12) Got them at ePassportphotos.com via Snapfish. So much cheaper!

Postcards/decoration for house
World Map [Great for decorating the house and the neighborhood kids love them!]
Book of puzzle
Stationary/greeting cards
U.S. stamps
Freeplay Energy Hand Crank LED Lantern
Hand-Crank Flashlight [very essential! I also wish I brought a headlight since those frees up your hand if you are trying to cook in the dark, etc.]
Nalgene Bottle
Reliable Watch
Travel Alarm Clock
TSA Approved Combination locks [these were useful. I used them to always lock my bags when I was traveling, just to give myself a piece of mind. The number combination is nice since you don't have to worry about losing keys.]
Calculator
Good quality umbrella
French pocket Dictionary
Small mirror
Duct Tape
Jump Robe
Gifts for Locals
Inflatable globe ball
Boxes of Crayola crayons (2)
