I don't know how old you are so I am going to answer this as if you are fresh out of high school, heading to college, and getting ready to live on your own
You can find many cook books that are geared specifically for those who haven't got a clue how to cook or bake. Just go to a bookstore or Walmart of even the library and look through them to find recipes that are easy to follow, won't cost you a lot, and contain ingredients you can eat. If you are allergic to or simply don't eat anything that would seem to be a big ingredient in a recipe, it is likely that none of us would be able to help you as far as recipes go.
Magazines usually geared towards woman and homemakers have easy to follow recipes as well. You could probably find neighbors or friends who have copies of magazines like Woman's Day or All4You, even Reader's Digest has receipes in it. Hospital waiting rooms or doctor's offices usually have random copies of magazines so the next time you visit, take a few and then just rip out the recipes you can follow and use.
You can also, as the first poster suggested, watch programs on TV. The Food Network and channels such as that often have shows just for those who want a quick, easy, inexpensive recipe that isn't going to taste like fast food. Anything with Rachael Ray is going to give you that. You can also go to both of the websites for quick and easy meals.
The winner of the last The Next Food Network Star also has her own show now called Ten Dollar Dinners. She takes simple ingredients and makes gourmet meals in a flash. And she's very personal and great to watch and is loaded with tips.
Just to start off with, you will need a selection of each of the following:
spatulas - various sizes (wide and thin), styles (slated and flat), materials (plastic and metal)
knives (just buy a set in the wooden blocks and you should be good as it's got several styles and often, scissors too)
mixing bowls of various sizes and a blender if you plan to make casseroles or cakes and don't want to kill your wrists by stirring constantly
spoons and forks in the large, mixing sizes in both plastic and metal. you will need these for stirring soups, sticking into meats, and mixing ingredients if you cannot use or do not have a blender.
set of pots and pans. any of those will do. or if you already have several of some, just buy what you need. most recipe books will tell you what dishes you need in order to cook the food.
baking pans and sheets, casserole dishes, things like that generally run higher in prices so try to find them through yard sales (don't buy something that's really scratched up), local charity stores, or buy them when they are on sale or ask friends if you can borrow a few things until you get a feel for what you really need.
you can find a lot of the utensils at Dollar Trees or Family Dollar. it sounds like a lot of stuff but you don't have to spend a lot of money to prepare your kitchen for cooking and baking.
