Looking good! The note on the landing gear picture should say "Leading edge" instead of trailing... but other than that - it's right on. 1/16 or 1/8 ply triangle shaped fuse doublers in at the point directly above the gear should do the trick(attached to fuselage sides and floor where gear mount). Don't worry about the gap in the inboard end of the ailerons, that's pretty much just asthetics and shouldn't make any noticeable difference in flight.
