Thats great man, congratulations. Just one, well two pieces of advice:

1) When your wife to be askes you about which flowers, colors, cake, etc... you would like at your wedding/reception, (even though you probably wont give two buckets of monkey piss) give her an answer. Then when she disagrees with you and goes with the exact opposite on every single thing she asks, just go with it and act interested. The last two weeks prior to our wedding, we wanted to kill each other. We've been married for 12 years this year and 11 of them have been in the USMC so if you ever need some advice (and you will) just ask.

2) Buy all the razors, hones, strops or what ever toys you want now.

Just so you know, the only food that has been scientifically proven to ruin your sex life is....wedding cake!

Seriously though, I wish all the best for the both of you.
