Laura, Draw length is measured the same way with all bows, 1.75" plus the distance from the string to inest of the grip where hold the bow.
It's the same for compound and recurve.
I think if you are shooting with proper form, your draw length won't change from compound to recruve/longbow. I believe alot of people have this problem of losing draw length becasue they are either overdrawing their compounds to the back of their heads, or they're not coming to full draw with the longbow. It's easy to let your form collapse with a traditional bow, but if you have good form you should keep all your draw length.
Regarding the arrows. I shoot mostly 3555 shafts, from bows around 40-45# @ 25" and at full length I usually need around 175-225grains at the front of the arrow to tune well.
I think that with a 32# draw weifght, you will be best served by some 1535 (or any other .600 spine shaft you like) at or near full length. From there you can use tip weight to get the proper flight. My guess is at full length wqith 100gr point they will be too stiff and at full length with a 250gr point they will be weak ... but somewhere in there is a good tune.
