I know how to send, the problem is my last 5.  No matter what I try, the amount I try to send is too high.  It says I have an unlocked balance on 5.34 XMR, and I put in:  Transfer <poloaddress> 2 <ID>

But it still says in red text there's not enough coins for mixin.

Possibly your tx was invalid and got rejected by other daemons. Had you sent a tx from the same address, but using another machine, within those 1149 blocks ? If so, you probably unknowingly double spent.

In any case, if you use a recent enough wallet, you should see that last tx as "pending" in show_transfers. If it indeed hasn't propagated to the network, you can "flush_txpool" in the daemon, and the wallet will soon notice it and switch it to "failed". There is a bug (fixed in the rct branch) which will need you to run "rescan_spent" after that in order to get the right balance.

But first, wait for the chain to be synced.
