I am a member of Milesource.com as well and I find this one a bit difficult as it takes a lot to get miles. One suggestion to getting miles is to buy things that give you points and free shipping and return the goods to a retail store such as GAP. Triple points this month is nice but still takes a while to get anything. One is probably best cashing in miles for a gift certificate from Giftcertificates.com then redeeming the GC for an American Airlines voucher. With that, you can travel and accrue more miles rather than spending them.
