Bringiton,
You can buy an upgrade on SW that lets you board in the first wave, which gives you the option to avoid middle seats. I don't remember how much it was, but not a deal breaker. You still have to get in line based on arrival.
Another option is if you have a disabled car plackard (from TX or other states, not an issue), or can get a temporary one right before your trip. Either the Blue or Red plackard will get you in preboarding. The red (temporaries) still require a doctor statement, and may cost a few bucks.
