Hey Vin, welcome to the riparium club
(unofficial)
That's a really interesting format tank, I can't wait to see your plans for it 
I would take a gander at ripariumsupply.com and crazydaz's thread on TPT for some super sick rip inspiration, mine is pretty basic and I am not doing anything about humidity control, as can be seen from the tips of
Here are some of the plants I have and used:
Aglaonema simplex (in another tank)
Aglaonema minima (in another tank)
Cryptocoryne ciliata
Cephalanthus occidentalis (cat palm)
Lysimachia (creeping Jenny)
Pilea grandifolia (aluminum plant)
Echinodorus cordifolius 'Tropica Marble Queen' (Spade-leaf Sword)
Ruellia 'Katie' Dwarf Bluebell
Cyperus Dwarf (umbrella Sedge)
Alternanthera dentata
Oplismenus Basket Grass (in another tank)
Spathiphyllum 'Golden Glow' (from Eric)
Asclepias curassavica (mexican milkweed)
Zephyranthes Pink Rain Lily
I got most all of these from hydrophyte (Devin) on SCAPE, he has the same handle on most all other forums too so you can google his handle
Some other worthy mentions are
Gibasis geniculata (Tahitian Bridal Veil)
Cryptocoryne lutea
Eleocharis montevidensis
Hygrophila pinnatifida, and most ferns actually
Many of the Bucephalandra sp. will grow emerged (but need humidity) as will some of the Anubias (careful with shrimp and anubias) and certain Crypts will all emerge and grow, as well as certain Hygrophilia. So many options!
For your filter, if this is going to be a shrimp tank too, I'd consider a 2213 PLUS a sponge filter and aquasoil, but I would really consider using the riparium planters and trellis rafts from ripariumsupply.com, they are very handy.
Lighting is all about the plants, not the substrate. If you are going to grow emerged plants then the light needs to be where the growth is, above the waterline and above the leaves. You can probably start the light on the rim of the tank but you will either have to raise it as the plants grow, or install a second light higher up so the plants "reach" for the light; remember, you are emulating the sun 
I have amano shrimp in my riparium but I think those things could live anywhere! I'd be interested to see what you come up with 
Have fun researching your build and keep us posted
