Sounds like you are encountering some fun hurdles. You will remember them when you go to upgrade to a 150g tank and things will go more smoothly. I was pondering doing a verticle overflow to a hole in the bottom of the tank like you are doing or notching the top back of the tank and putting a catch box on the back. I decided, thanks to some info from the gods of RAG to just plan on putting a hole in the back left a couple inches under the waterline and do some pvc and an elbow up and water will pour into the top of the pvc, down, out and down to sump. Should do well but your idea sounds good too. Get those pics up so I can see some ideas :P G/l with everything and hope the frustration doesn't get to you too much!
