Ok, say your building an Emeraude and your not looking to make it a
speed demon, you just want to close up a few gaps. As your building the
wings, you realize the sizable gaps at between the wing and the flaps, &
ailerons. What would anyone recommend to close these up while in the
building process instead of waiting until it's finished.

Google "gap seals" and you'll have all the info you want on that.

Also what other reccommondations would anyone have (besides building a
different plane) for plain old cleaing up the efficiency of the plane?

To second John's recommendation, "Speed With Economy" by Kent Paser would
be an excellent starting point.
