if i payed $1000 for a 1.3 ghash/s system, i could pay that off in about in a little over half a year at this difficulty. ($0.14/kwh)
I'm not familiar with how difficulty increases (how often, how much) so how long would it take to payoff the system if the BTC price remained the same but difficulty increased as it is now?

I'm not sure about the timeline for paying it off, but maybe you can cut your initial costs.

Do you have a part list put together? $1000 seems high for 1.3 Gh/s. Assuming you live in the US.

http://www.alloscomp.com/bitcoin/calculator.php is a good little calculator

The difficulty increases every so many blocks and its based off of how fast those blocks are found.

Check the top of http://bitcoincharts.com/markets/ to check.

That calculator doesn't account for a difficulty increase though
