Whats the benefit of an external preamp if the tt i am considering already has a built in phono preamp? the signal to noise ratio is 55db i believe.

It's completely redundant and unnecessary unless quality of sound is your concern. In theory, an high-quality external phono preamp will sound better -- or even much better -- than the cheap one built into your turntable. But everything varies, and since this preamp costs like 1% of a the cost of a serious high-end phono preamp, it's possibly no better than the one that's built-in. Also, your turntable *must* have a switch to bypass its internal preamp, or else you won't be able to use an external one at all (you can't feed a phono preamp into another phono preamp).

What advantage does the 1000ma ac adaptor have vs. the less expensive 500ma version?

It's commonly held among audiophiles that almost any amplifier can be made to sound better if more and cleaner current can be made available by up-sizing the power supply. This SMPS regulated adaptor can supply twice the current our standard one provides.

Does this filter out under 20Hz (could be a band-pass for 20Hz-20kHz)?

Frequency response drops off sharply below 20Hz; down 10dB at 10Hz. 20dB at 6Hz.
