Welcome to the forum Eric.
I have not seen a Scepter V yet, but some of your questions are common to the Shadowcat that I have.
Draw weight: The bow has three ranges of weight 40 to 50, 50 to 60 and 60 to 70 pounds. You will need to decide which draw weight range will suit you, and within each range there is 10 pounds of adjustment. I shoot 3D competitions and prefer an arrow velocity of around 300 fps, so I have a 50 to 60 pound bow, adjusted to around 58 pounds. I hope that helps.
Draw length: There are two cam options, and with your DL of 32" you will need the Nitro 2.0 cams.
I can't give you any feedback on the Scepter, but I am told it is quieter, smoother and more stable in the hand than the Shadowcat, which would be quite something, as the Shadowcat is already an excellent bow.
A bit of general advice: You really could do with trying some compound bows before you buy, as they are very different to recurve. Also, it would be helpful to know what you will be using the bow for (target, 3D, hunting) and whether you will be using a release aid, or fingers to loose the bow.
Keep asking questions, there is an huge amount of knowledge on this forum, including Martin factory staff.
