Going to be replacing the resonators with a pair of glass packs and running straight pipe out the back from there. My question is this: will the amount of straight pipe affect the sound put out by the glass packs or will it still have the same throaty sound that it would if the glass packs were mounted where the stock mufflers are?

Glass packs will affect the sound if they are the only muffler you have. The length of pipe after the packs will have little effect. You should get a deeper tone, with the longer the glasspack the quieter the sound and deeper the tone. If the glasspacks are behind another muffler they mainly cut volume with little to no effect on the tone. I use 12 inch glasspacks behind the axle when the chosen muffler is either too loud or the system has too much resonance, and the tone doesn't change. My parents use really long glasspacks, like 48 inchers, because they like them, so I have experience with both ways to use.
I'm trying to figure out what will be the loudest, glasspacks where the resonators are and straight out from there, or Flowmaster 44's in place of the stock mufflers, keeping the stock resonators. Trying to do this for around $200, which is what the glasspacks would cost for installation.

The loudest would be no mufflers at all. If you want something in there, 12 inch glasspacks, and step the inlet/outlet diameter of the packs up so that the inner diameter of the muffler's interior (not the inlet/outlet pipe) is the same as the system's diameter. I doubt you'd like it though.
Consider the exhaust shop's stock welded case muffler in place of the Blowmasters. They are about the same but cost less, and will last just about as long as the Blowmasters will rust out along the internal baffles in a short amount of time. My last set (and I do mean my LAST set) lasted 2 years.
Hey, if you want a really good sounding exhaust, consider the Powerstick. This style muffler was the factory option for the 1970 Chevelle SS454, and they sounded outstanding. Had a set on a 99 Silverado back in 2000, and it sounded so sweet I'd drive for miles on the road running it up then decelerating over and over just to hear the pipes. My next system on my truck will be these, current system was a set of Walkers because when I put it on the truck was the wife's daily driver. Now that she can't drive, it's MY daily driver.

If the sound you are looking for is loud, annoying and raspy with a lot of crackle on the decel, then yes. Short glasspacks get annoying quickly if they are the only muffler on the car. You can go find glasspack systems on Youtube to get an idea on if that's what you want, but I also encourage you to check out the Powerstick system. You will of course need a resonator with the Powersticks, just to get a bit of resonance out.

My 71 mustang has glass packs behind the headers and straight pipes out the back. Sounds awesome, but would drive me nuts on a daily driver. It set off car alarms nicely though.
Inside diameter is something like 1 5/8" on the V6 (I measured this over 10 years ago when I got the Magnaflow and might be a tad off, but that's what I remember). I imagine, as the systems should be the same, the V8 is the same.

I would, but my daughter's car crapped out so she's driving it until I figure out what the problem is. Chevy and their stupid BCM crap, why does it require a computer to roll down a window?
Sounds like the Magnaflow diameter......
