Maxi jets are fully-submersible. I don't think the venturi air injection works when it's too deep, but you don't want to use that anyway. They let out a lot of flow for their size, as long as their intakes don't get clogged with junk. Most importantly, Maxi-jets are known for their reliability - a lot of other brands just don't last. You're correct - they're not adjustable flow - mini-jets are adjustable, I believe, but they don't get as high as say a Maxi 1200.

20x can be too much for some coral species. You can position your PH's and live rock to create the right combinations of light and flow in different spots to best grow different coral, but if you're planning on having lots of species that prefer low-moderate flow, then yes, 20x is too much. Also, even many hi-flow species won't enjoy being right in front of the blast of a big powerhead - more important is lots of turbulent flow hitting them in random directions.

Your person at the lfs obviously is a greenhorn when it comes to PH's since maxijets are the STANDARD to which all others compare themselves to. They can be fully submerged, and depending on what corals (and what kind of tank) you get 20 x is not too much water flow. Corals that want less water flow can be placed in an area that doesn't have as much water flow. I wouldn't worry about an adjustable flow, get the maxijets... You won't be sorry.

I wouldn't think 2 is too much. Your profile says you have three leathers. Leathers like flow IMO. Some with SPS even have upwards of 4. I have about 15X in my 90 gal and it could use a little more. Think of it like this. If our tanks had flow like in the shallow reefs, we couldn't keep the water in it.
