You've got the 1-4L, don't see where the 70-300 adds much. And with the 24-105L, why bother with the 28-135? If you're serious, I'd sell the two non-Ls and get a 50mm 1.2 or the 85mm if you really want to splurge.
Without knowing what kind of shooting you do, it's somewhat pointless to recommend lenses. But that's me, the dullest pencil in the box.
I really agree that a fixed, fast prime is handy as in the 50mm mentioned above. I have the sweet and fast Nikkor 35mm f/1.8 (semi wide angle - prime) for my "street lens." (less than $200).
