Shrimp aren't terribly demanding, really. Planted tanks are definitely good for them - the more surface area the better since they feed on biofilm that grows on tank surfaces.
I've successfully kept them in tanks with canister filters, hobs, internal filters, power heads, and sponge filters. The two bonuses of sponge filters (HMFs included of course) are more surface area for bio film and you don't have to worry about a foam or mesh screen on the filter intake to avoid sucking in shrimp.
Above all - no ammonia and no nitrite. All of my tanks have little to no nitrates on account of plants, so I really couldn't speak to their effect.
Shrimp don't need to eat a lot and they'll thrive just fine on whatever's left over from feeding any fish that might be in the tank. If they're in a dedicated tank then limit feedings to every 2 or three days - and pull the food out if it isn't eaten within a few hours.
I feed Ken's veggie sticks with calcium and dried nettle leaves in my shrimp-only tanks, but they live off extras in several of my other tanks.
