The only thing I would add to the suggestions above is that Bitcoin (at the moment) is so popular that the mining network is running several thousand (100K+) transactions behind. The negative effect of this, is that people are competing to get their transaction written onto the next block by upping the mining fee donation. In some cases this can be as much as $20-$50USD, so very expensive to send small amounts from one wallet to another. If you leave the fee set to a more reasonable level (<$1) it can take days to get picked up by the network. In my opinion, Litecoin or DASH would be better currencies to use for small ($1000 or less) transactions at the moment.
