Boomy Bass vs. Cabinet Volume

I'm currently working on building and designing my first pair of tower speakers. It uses pretty cheap drivers because i'm in college and for all intensive purposes it will be a party system (the secondary purpose is to show my dad how easily outclassed Bose is because he has a tendency to buy into brand names).
The drivers I'm using:

• GRS 8PF-8 8" Paper Cone Foam Surround Woofer (8; 4 in each cab to retain 8 ohms)
• Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter (2; 1 per cab)

I'm using a third-order cross-over 2400 hz; hand-made not prefab. I'm also using a zobel network on the woofers. The cab is going to be sealed.
My Questions:

• First Question: What causes boomy bass (monotone; non-responsive sound; airy; muddy) in relation to enclosure size; an enclosure larger or smaller than the vas? (i've recently seen conflicting information on this and i'm new to this; feel free to throw in any other factors)
• Second Question: Does the zobel network (resistors) need to be rated for the amount of power that the woofers will receive? Or does the zobel network receive less power than the woofer?
• Third Question: Since the tweeter is only receiving a small portion of the spectrum (upper 3 octaves pretty much), what could I expect for overall power handling for the whole speaker collectively before I would risk damaging the tweeter? I realize this changes with the spectral distribution of each song, but just generalize.
• Fourth Question: With said drivers, would it even be useful to use goodish crossover components? Or might as well I go bottom of the line (non-polar electrolytic capacitors, etc)?
• Fifth Question: Will the woofers be over powering compared to the tweeter? The woofers have a lower sensitivity than the tweeter, but there are 4 per cabinet and I'm just assuming that to a small extent that will increase the effective sensitivity.

Any advice, suggestions or criticism welcome. I know there are cleaner speakers I could make for the money, but this just seems to fit my needs (and I love the sound of paper woofers). Also, ignore the specs that say the woofer is only good down to 55 hz. After reading many reviews, this speaker is apparently prone to a long break-in period but will get down to about 35 hz after some time.
