1. Collect all your soiled clothes from the rooms, or wherever you keep them. Keep in mind to look under your bed. Make sure you find everything.
2. Sort the clothes into piles. There are two important considerations here: what kind of fabric is it (as in sheets, towels, bathrobes, napkins and rags) and what color.
3. Remember, towels and sheets should not be washed together. The top load washing machines should be used for towels, and sheets should be washed in front load machines (They are less harsh on sheets so they come out with fewer wrinkles).
4. Sort the remaining clothes (generally materials such as cotton, linen, synthetic fibers) according to color. All whites should go with only whites (or very light colors if the item has been washed many times). Then put all the reds, pinks, and oranges in a separate pile (never keep this close to the white pile as you will be wearing pink shirts for a long time). Then, depending on how much more you have left, put the other colors together, possibly into a lighter (e.g. grays, yellows, light blues) and a darker pile (blacks, dark blues, browns, greens, purples).
5. Know that each pile is its own load. It is recommended to start with the highest priority pile, usually the one with towels; you need to get them done since they take more time to dry.
6. Top load machines --First turn on and let the water run into the machine, then add 1/2 cup or one of the small plastic cups full of laundry detergent. Put the first pile into the washer. Do not overload the machines!
7. Understand all the knobs on the machines to make sure you are washing the clothes the way you are planning to. *White or light colored clothing usually goes on hot temperatures.
8. Close the door and push the on/start button.
9. Return when the washer is done and take the clothes out. Shake them gently, and put into a dryer to dry or you can hang them on a clothes rack.
I'm not sure how old you are, so it makes it difficult to suggest clothing stores.
If you're in high school still... a store selling brand names like Roxy would be good if you're into that scene. Tilly's, Macy's, and other surf shops specialze in that. If you're looking to save money, Nordstrom's Rack actually has the brandname clothes at at least 30% off!
Other stores you can check out would be Wet Seal, Charlotte Rousse or Forever 21.
If you're older and in college, then you have more options. Old Navy sells fantastic items that are decently priced and are fashionable.
Post-college, I'd suggest the Gap or even Express Fashion. They're both great stores that cater towards young women in their 20s -- and aren't terribly expensive.
Just wear whatever you feel is comfortable and stick to the sales -- saving money is great because you can buy more!
