While the low-end M-Audio monitors are nothing exceptional or anything,
they are waaay better than crappy Creative computer speakers. Good
decision.

I've heard very good things about the EX series (people comparing them
with the low-end Adam and stuff like that!) but they are much more
expensive.

You may be able to find an adapter that provides phantom power but it's
probably best to get a mic preamp. You seem to be an M-Audio fan ;-) so
look at M-Audio's, they're not too bad for the money and they do provide
phantom power:

Myself, I'm using the Studio Projects VTB1 and it's OK:

A good studio monitor does not need treble/bass control. That's the
purpose of a monitor - to provide unalloyed translation of the electric
signal into sound. If you do find you need to apply spectrum
corrections, you actually need to get a better monitor, or fix your
room's acoustics, or most likely both.

If you can afford it, subscribe to Sound On Sound. They run monitor
reviews quite often and each issue carries an article about fixing the
acoustics of small amateur studios. Extremely informative!

That being said, you can apply all kinds of filters via LADSPA. Install
JACK, install LADSPA, install all the LADSPA plugins you can find - some
of them are EQs, filters, etc. Install JACK-Rack, insert it into the
audio chain somewhere, load up a LADSPA EQ in JACK-Rack and that's it.
