<div>When you say have the relays energized, I know you mean
energize the solenoid but do you mean by that that the relay
contacts are closed (power flowing) or open (no power)? I'm
guessing you mean don't go from open to closed while there's
power flowing since their will be a temporary arc? Could I
just use a normally closed relay and then use the
microcontroller to open the relay and cut the power if I need
to.</div>

For safety reasons, you want the relay to disconnect if energizing
power is removed. An NC contacts will not break the circuit if you
have power control problems to the energizing coil.<br>

<div>Do you have any links to those higher cost relays? I would
really love to actually make it so that I could have a button
on the front (hooked to the uC) that would allow me to, using
the relay, turn the power on or off to any of the outputs. So
having one of these nicer relays, if not too expensive, might
be nice.</div>

Look up "contactors" for relays designed for high currents and
regular switching.<br>
