Well sometimes, but this is rocking the boat in your case since you seem
well suited to this routine normally.
Re setting a non CO2 tank is different.

I'd just use tap, especially on a non CO2 method.

That's normal, nothing to worry about, test the pH right before the lightrs
come on and right before they go out.

Well, there's the issue. The pH goes up because the water is losing CO2(a
weak acid) due to plant uptake.
For non CO2 methods, 2w/gal is a max light level.
You have way too much light for not using CO2. Either plan on using CO2
with this light level or lower the light level to 2w/gal or less.

This is common in planted non CO2 tanks, this plant does very well and
forms a tight low carpet, in CO2 tanks it'll grow upward much more.
The other two leaf per node pearlgrass also does well under non CO2

Not too much generally, it speeds things up and helps the plants grow
Flagfish and barbs are useful, shrimp also.

Well, estuary plants, many of which are emegernt plants.
Ruppia maritima is good, I'd just gom all the way and keep Saltwater
perswonally, thenm you have 100 species and VERY cool fish to pick from.
Puffers included, some of which are very interesting fish.

Try some Ruppia. Few plants will make it and it's not enough for full SW
Emergent plants, Mangroves etc are also nice looking options.
