Paper Princess is right .... don't touch that quilt with FMQ until you are no longer nervous about FMQ!!!
Practice, practice, practice!!
Practice a few different techniques to get the hang of it, and practice a lot more on the specific techniques you plan to use.
I keep a bag of batting pieces around and make practice sandwiches before I start all of my quilts. I practice the technique/pattern I am going to use with the thread I plan on using - I try to use the same fabric, and so far I've always used the same batting.
