Just got new covers for the overflows (2 universal drain hair catchers from home depot; plastic and can be cut to size--they fit perfectly into the 1-1/4" PVC--a little pricey but they work wonders). The overflows are keeping up with the pump and now all I have to do is make sure they dont catch air and lose their siphon over time 
Thanks everyone for your input!--im finally making my tank happen!
