I can't help you with the shrimp issue unless you're willing to get a larger shrimp, such as amano shrimp. Most fish will eat RCS, especially the babies. If you set up the tank to be heavily planted, some RCS may be able to hide for survival, but then you can't see them either. Plus, you'd have to consider the shrimp getting sucked into the filtration. Overall, I'd recommend amano shrimp for what you're wanting to do.
I'm not nuts about Flourite. Too messy. I prefer Eco Complete.
I'm not the greatest with lighting since the WPG rule has changed, but from the little bit you offered, it sounds like you're headed into trouble with such high lighting. Maybe if you posted more info about the exact fixture you're talking about getting it can clear things up (maybe it's a really poor lighting fixture so the light isn't as bright as it sounds). If you're talking about anything close to T5HO, then you're definitely getting too much light.
Injected CO2 is the only way to go. Good move. I suggest using a reactor. I run Rex Grigg style reactors for my tanks, but the Cerges are the latest style. Either should work fine.
Fertilizer needs to be started as soon as you turn the lights on while plants are in the tank. I recommend dry EI ferts. Super easy and super cheap, and also the best you can get.
As far as filtration, definitely get a canister. I'd recommend two quite honestly. Take the money you were going to spend on the overblown lighting and put it into your filtration. You need a canister to run the injected CO2. I started out with Emperor filters and finally just tossed them. Now I have a total of 8 Rena XP canisters running my tanks. Only my nano and QT tanks run HOB filters. If you are on a tight budget, look for used Rena XP3s or XP4s. You can get a really good filter for an excellent price. They are workhorse canisters so used ones are still very much worth getting. I have one Rena XP4 that's 5 years old now and still running like new.
