Mike, from the references to available gain in that post, it sounds (pardon the pun!) as if you have enough gain available for the full ±15dB circuit you started with or, at least, somewhere in between.
Absolute component values aren't important so, as you have two sets of component values in front of you, you can experiment with whatever intermediate values you have available to get the range(s) of adjustment you want. As it's completely passive, there is no way you can do any damage!
EDIT
I got interrupted while I was composing this post, so missed the your last one, Mike.
I think this post really answers your question - experiment as much as you like until you get the result that you want!
