It's not going to hurt your regulator to have Argon pass through it. If you use it to check your argon bottle, just purge the reg a bit when you hook it back up to breathing gas, to get the argon out of the hoses.
There is no problem with leaving your suit inflator hose on your first stage, but it's kind of difficult to figure out where to put it that it isn't dangling and in the way, and is still accessible for the dive.
I've found having our own tank pressure gauge has been awfully convenient.
And I don't do mix dives without being darned sure I have a full Argon bottle
