That looks like my portfolio about 3 years ago. What are your fliying patterns?
My strategy was to earn to topoff and redeem for domestic awards in the programs I was going to dump. Didn't pay for a single flight in 2008

. At minimum you will want to winnow down UA/US/CO to a single account unless you are flying two of these a lot. US is not a popular choice but if it works for you, all the better. I would abandon the UA and F9 accounts and looks at possibley converting CO to Amtrak points, if you use rail.
Also, why no Alaska account? You can deposit future DL and AA activity there.
