Rice Dream is a good rice milk (it may take some getting used to, but the chocolate should be easy to adapt to!).
Hemp milk is also good.
Living Harvest hemp milk is good (but be warned: there is another brand out there, very similar name, that is nasty!)
You can make your own almond milk by soaking raw almonds overnight, then rinsing and blending with about 2x the amount of water. Strain through cheesecloth, and add a dash of salt and sweetener as desired. You can also add vanilla extract. You can also make non-dairy milks out of macadamia nuts (very rich, great taste), brazil nuts (good source of selenium), cashews, or any mix.
For meat replacement, there are many meat analogs available, like burgers, hot dogs. But many of these are very processed. I recommend getting away from them as much as possible. Instead, explore the wonders of traditional vegetarian foods from other countries. Vegan Planet is a good cookbook that has a wide variety of recipes.
Cheese replacement: most are pretty gross, IMO. There is a new one out called "Cheezly" that is supposed to be really good.
www.veganessentials.com carries it. Another option (besides just transitioning away from cheese and substitutes) is to make your own. The Ultimate Uncheese Cookbook has recipes that are supposed to taste better than any of the premade stuff out there (and are made with healthier ingredients).
www.vegsource.com can give you some more info.
