#1: I like the Behringer.
#2: You can plug an acoustic-electric into an electric amp, but you are not going to get that full-bodied acoustic sound. Electric amps are made to distort sounds. You can plug an electric into an acoustic-electric amp, but, you are going to have a cleaner sound some musicians don't prefer for an electric guitar. If you want to see for yourself, go down to your local shop and plug an electric into an acoustic-electric amp or vice versa, you'll instantly notice the difference.
#3: it depends on what kind of amp you get, if you toggle the controls around enough, you can probably get the sound you're looking for, although acoustic-electric amps tend to have distortion knobs similar to electric amps. The only difference is that it does not distort as much
reasoning: try this, finger a chord shape, any one, on an electric without plugging it into an amp. strum. Hard to hear isn't it? This is because the sound is meant to be pushed through different parts of the amp (becoming a bit distorted along the way) then pushed out into the air.
now, finger a chord shape on an acoustic, again with no amp. strum. louder isn't it? The acoustic guitar is made to amplify it's own sound without the help of an amp, thus the sound hole.
sorry to ramble, but my guitar teacher gave me a huge lecture on this and I'm happy to share it with someone
anyways good luck, hope I helped!
