Congratulations on your bee-venture. Take it from someone who got his first hive last year, they are habit forming. The more you learn, the more you'll realize how little you know. About the time you think you have them figured out, they'll change.
The reason behind all the swarming was being to crowded in the nuc. I personally think you need at least two deeps for brood chambers and the medium for honey. Most of the time, you aren't handling the deeps as a whole. I'll soon be 75 and I have no trouble handling a ten frame deep. If it seems to heavy, I pull a few frames.
