They are rated to respond up to 1000 Hz, and if you keep them lp'd at about 100-200 Hz (your ears, your preference) they'll do fine as lower end midbass fillers (if that's what you are getting them for). Are you running another amp and sub for the sub stage? If not, then lp those EF-8's at around 60-70 Hz and they should do a decent job.

Yes, I'll be running either a Diamond D6, 2 Diamond D3s, or an Fi Q. I know that the EF-8s will be good for midbass, but will those frequencies (100-200Hz) be high enough to be directional or can I run 2 EF-8s on one channel?
At 100hz you might be able to get away with it (but at that point, they'd be running such a limited bandwidth that using them would be a waste of money, power and real estate anyways....)
Going much higher than that, and you would really want to keep them in stereo.

That is correct. Does anybody have any Idea of a good 6-channel amp that isn't outrageously priced?

How much power are you planning for the sub stage? Will the sub channel in the Belle work for your sub(s)? If so just get a Memphis MCA-150 to run the midbasses and use the sub channel on the Belle as intended.
There is not one that makes any type of power really.
3 way actice front stage plus sub, requires 3 amps to do it correctly to my knowledge.
CDT makes a semi-adjustable 3way passive crossover. I do not know if the belle will allow you to bridgethe channels twice (like running a 4 channel amp) and then run a sub amp. In this scenario, that would be the only amp you would need.

No, it won't be enough. I'm using an Orion XTR Pro 1000 that I just bought off of BigBirney420 here on the forums. The big Memphis Belle would work, but it's also too much $$$. Besides, I just bought the Orion and I want to use it.

Well i have an Eclipse EA2212 2-ch amp that is low enough power that I could probably use it on the tweets. Are there any decent 4-ch amps that could power the mids and the EF-8's? Also, what are the impedences on the separates (mids and tweets)? I'm guessing it's 8 ohm, then the bridge them down to 4 when you use the passive crossover in a normal component set. Correct me if i'm wrong
Most car audio (with the exception of infinity kappa series coaxials) are 4 ohms.
You will also want to make sure you can bandpass the mid. I think Diamond Audio makes a 4 channel with this capability, if you do not have an active crossover.
If you want to run passives, then get that 3-way crossover I was talking about. Leave that eclipse alone and get a 2 channel appropriate for your listening needs. I have ~100w on my 3way passive set and it works just fine for my ears. I wouldn't mix passive and active in the front stage.

How then, does a normal Component set, including passive crossovers, achieve a 4-ohm load on each channel when there are 2 speakers (1 mid, 1 tweeter) per channel?
From my understanding, the crossover blocks frequencies along a path. The only time resistance changes is when there is a L-pad along the circuit to attenuate the tweeter. That changes the signal to the tweeter, not the characteristics of the tweeter itself.
I would say to hook up a dmm to each part of the componet set, and then hook it up and the resistance should all be ~4 ohms.
That is just my understanding, which may be wrong

Where can i pick one up. Any idea on what good brands are or what the average price is?
Pick what up?
