You need two commas or none.
"John didn't want to go and, quite honestly, I didn't either." Note that the comma goes after 'and' in this case.
No, that would be too many. You do need commas around an interpolated adverbial phrase like "quite honestly". And when that's necessary you don't put a comma before 'and' as well. Besides, it's not a strict rule about commas between independent clauses: "I ran into the room and I sat down".Don't you need a comma before 'and' because this coordinating conjunction separates two independent clauses?
