I learned from a set of cards a sister sent me. I have the cards reproduced here:

There are a number of teach yourself salat programs on youtube. You listen to those, and read along from the cards to practice your pronunciation. Then, stand to pray with the cards in front of you. Read the arabic out loud, and then the meaning in english silently. inshaAllah in a few weeks or months, you'll have it memorized!
However, if you can find a chance to sit with someone who knows the prayers well, do it asap! I learned to pray on my own, and after I got married a few years later, had my husband listen to me pray. I was pronouncing quite a few things wrong :embarrass
