I had been in ten weddings by the time I got married. I had mine planned in 3. Weeks and then i enjoyed the next few months getting my house ready to sell and then move. Don't stress. Make the plans and then don't worry. The day will happen and you will survive. Don't sweat the small stuff. Communicate expectations and make a plan to execute it.
Weddings are not broadway productions. Or at least they should not be treated as such. Have fun!! Congrats!
