if you dont go this way, you would only NEED one bubble trap in your original design, right before the return pump.
as for drilling i suggest looking into glass holes for an overflow. if thickness is a worry ive drilled 2 holes into 1/2 inch glass. youtube.com has videos on how to drill a tank.
welcome to the forum.
+1 on the unions LOL i just had to take my pump out for cleaning and what a pain in the butt that was.... oh well there is always the next tank ........
