Please advise on this comma among semi-colons and provide a more concise sentence

I created this question for two reasons:

1. I want to know if it is proper to place a comma after the word and (in bold) below.

2. This sentence is kind of clunky, like many of my sentences, and it helps if more advanced writers chop it up and express it in a more clear format. Please offer me your re-written sentence, and tell me why you changed it.
