Help - where should I put my comma(s)?!

[BecauseImWorthIt]

This is the sentence, without any commas:

"We have not reviewed this in full (and indeed the ISO 20252 standard has to be paid for) but there are a couple of issues that have to be raised here:"

And this is what I have written:

"We have not reviewed this in full, (and indeed, the ISO 20252 standard has to be paid for,) but there are a couple of issues that have to be raised here:"

I seem to have completely lost the plot and can't work out if this is correct!

Help!

TIA

Midnightexpress: it's wrong, it's messy and anyone can write a book. You are the weakest link - goodbye!

And you're very rude funk.

I'll leave you to it, since you're so very sure of your own genius.

Midnight: I never claimed to be a genius (sorry if my dry sense of humour upset you, I didn't mean to be rude!)

Please tell us how many copies of your book have sold and the title. I'm very interested. Thank you.

The Oxford comma is when the 'and' comes after a comma - 'Red, white, and blue.' I can't think of any instance where a comma would go after an 'and'.
