I have one, so I'm probably somewhat biased, but I'd say the 2213 is a good choice. The flow rate wouldn't concern me, so I'd suggest sticking with the 2213 versus the 2211, particularly as they're fairly comparable in cost (from what I've seen). Plus, it's always better to have more filtration than you need than to spend money twice.
As to reducing the flow, yes you can do a number of things. The valves on the quick connect can be used to restrict the flow, you can drill the holes in the spray bar slightly larger, you can plumb things (like heaters or CO2 reactors) into the line, etc. Try it without anything and see what you think. You may decide to reduce the flow, but I don't think you'll really need to.
