Jeff,

Here is an illustration to help with you with what I know to be acceptable in our local jurisdiction (see attachment):

Your second question:
"Harder question
2- There is two hoses (from what, I have no idea- couldn't find the source) terminating into a tail pipe that is p-trapped and then connected into the main sink drain arm. Any issues with this???????????????? (this sink was in the washer / dryer room)"

Again-- it all goes back to it's relation to the flood rim and what it is connected to...
Richard
