Congrats man! Best of luck to you.
My advise that i can give you after 6 years of marriage-
Save as much as possible before the wedding. You'll need it all.
Stay out of debt as much as possible while married.
Buy a house, mostly for the tax benefits.

Keep seperate checking accounts and split the bills each month. It's easier that way. That way she can't be pissed when you buy golf clubs. (Unless you miss the mortgage payment!)

If you're wanting kids, give it several years before you do it. Make sure you have everything in order (jobs, debts, and your personal relationship) before making that committment.

Other than that, just remember to have fun. Hopefully she'll be your best friend like my wife is to me. That makes it so much easier.

Best of luck.
