Hi Scott
This was answered in question 52 14 of this wiki and I cut and paste two papers recommended by Evgeny:
A Practical Guide to First-Order Multiplet Analysis in 1H NMR Spectroscopy by Hoye, Hanson and Vyvyan
A Method for Easily Determining Coupling Constant Values: An Addendum to “A Practical Guide to First-Order Multiplet Analysis in 1H NMR Spectroscopy” by Hoye and Zhao (2002)
If you start there you should be able to work through first order spectra.
