Hi,
Am not really an expert in anything and definitely master of none but some
things that have helped me include, perhaps look at using Compile. Use
packed arrays to convert internal Mathematica representation of reals,
integers etc. This saves memory usage more than anything and leads to
efficiency.
Most of what is written in C can be exchanged in and out of Mathematica
via mathlink. Its all documented in the help files.

Good luck.
Cheers
Yas
