You didn't mention it, but remember that the AS VISA card gives you a $50 companion ticket each year and using the card is now the only way to get the 1,000 mile online booking bonus. The AA online booking bonus is 500 miles. You might also want to look at getting an AS EasyBiz account to rack up even more AS miles since you own your own business now.
I second this. Being a NW flyer who often flys Alaska but also does a good bit of flying on other airlines Alaska's many partners make keeping all my miles in one account painless. I switched from Delta to Alaska some years ago just for this reason.
