As you describe it, this isn't really a schizoid tank. It's a fish tank
with a few minor neuroses.
For your first serious attempt at growing plants you should probably avoid
the pleco's and discus and instead start with less expensive and less
demanding species so that you can tailor conditions to the needs of the
plants, not to the needs of the fish. When you stock the tank, the first
fish that you need to think about are algae-eaters. There's a long list
of possibilities. My favorites are siamese algae eaters (Crossocheilus
siamensis) and american flag fish (Jordanella floridae). Check the
archives for other alternatives.

Not so good for CO2, but I understand that you can make it work. I can't
really envision how the biowheels figure in here - they seem unnecessary
given the big sump w/bioballs. I haven't done this but I understand that
to make this work with CO2 you need to make sure your sump is sealed to
avoid CO2 loss, and to lower the spray bar below the water level to avoid
surface turbulence (which promotes CO2 loss).

You need to work on this part a little more. This list gives my view
of the planning steps you need to use to start your setup:
1) what you want from your tank and how much time and energy you want to
put into maintaining it,
2) what plants you want to grow to meet your goals and as a sidelight,
how you want them arranged,
3) lighting for the plants you select and the maintenance time you're
ready to commit to the tank.
4) CO2, the need for which is determined by your choice of plants and your
5) substrate, of which there are several choices - including none
6) fertilizer to match your choice of substrate,
7) circulation (necessary) with or without regular filtration (only
necessary under limited circumstances);
8) other techno-gadgetry i.e. pH controllers (if you use CO2) and heating
cables (if you have a substrate).
The first item is by far your most important choice. If you want a lush,
dazzling tank like the ones most often featured in books and magazines
then you will need to commit a lot of time and effort to maintaining the
tank. If you want a more subdued look (which can be equally lush) then
less time will be required. If you want a few plants to offset your fish,
then relatively little maintenance will be needed and relatively little
success can be expected.
As with almost all things, your increasing experience will allow for a
a gradual reduction in the necessary time and effort.

Yes, I think you're asking for trouble. Certainly it can be done (at
least as far as the angels and discus go... I'd probably avoid the
pleco's) but it is best done by someone who already has experience with
growing plants. Keep in mind that a "serious" planted tank is fairly
demanding; if you try to maintain demanding fish in the same tank then
you'd better be real good at the balancing act.
