Aiming for a Green Thumb via Aloe Vera

For a change of pace, I've decided to buy an Aloe Vera plant to grow at home.  This is basically the first plant that I have ever personally taken care of, so we'll see if I have a green or black thumb.  From what I've heard, it's a relatively easy plant to take care of.  It is similar to a cactus, since it doesn't need a lot of watering.  It has a lot of medicinal properties, as it is used to heal burns, rashes, cuts, etc.

I bought my Aloe Vera plant from my local Home Depot for around $5 (including tax).  It's a lot smaller than the stock photo above, so I guess that's why it's a bit less in price than the one shown here.  According to the little thing that they stick in the soil (I have no idea what it's called), it looks like I need to water it weekly, fertilize it after every fourth watering, and place it in bright, filtered light, and warm weather (50-90 F).

Since it's winter here, the warm weather part might be a bit hard to accomplish, since my room basically feels like an ice cube most of the time.  I'll try putting it under florescent light for right now and see how that goes.  How do I even fertilize a plant?  Looks like I need to do some research.  Wish me luck!  (I'll probably need it.)
