Congratulations. Welcome to the club. Now you won't have to budget
money for buying kites, you will have to budget time to make kites. I
don't know which is worse... ;-)

I use a #14 needle for most sewing, including sewing the dacron
leading edge and reinforcements. When I sew the nose piece on, which
is often seat belt material, I might change to a #16 needle. I used to
use a #11 or a #12 needle on ripstop, but found changing between the
smaller needle and the #14 to be time consuming.

Theoretically a zig-zag is a little stronger than a straight stitch.
Usually commercial kite makers use a zig-zag because it is a slightly
crooked zig-zag is hard to distinguish form a straight zig-zag. I
believe that the difference in strength is not worth worrying about.

I use a decorative stitch to attach the leading edge, often in a
contrasting color thread. Strength is not that critical on this seam.

Bill Tyrell wrote an article in Kite Lines titled, "Mastering Nylon".
You can get reprints of this article from Kite Lines, or from Bill
(The Kitestuff Co., also known as, The Fabric Lady). This answers a
lot of questions about dealing with nylon.
