question about 4-disc 5 lug brake swap

I'm going to go for the 4 disc 5 lug swap on my 91 lx.

I'm going with '98 v6 spindles and hubs ( I know...8mm wider track on each side) in the front and sn95 axles in the rear.
My question is I'm afraid to get the axles and they might break on me if they have a lot of miles on them.
Is this a good opportunity to go for 28 spline moser axles or unnecessary?
What would you do?

Secondly...how much should the calipers/rotors/break pads run me?
I want the whole cobra set-up.
2003 cobra calipers and 13'' rotors for 1994-2004 will work right?

I was looking at this kit http://cgi.ebay.com/ebaymotors/Must...42605QQitemZ7997003005QQrdZ1QQsspagenameZWDVW

Do you think that's too much?

I've already read that site with all the brake info...just needed these things cleared up.

thanks

Actually what's really confusing me is on Matt's brake site it says I need to use sn95 calipers from 94-98 v6/gt/cobra for the rear when I use 94-95 axles.
What about calipers from 99-2004?
For the rotors it just says 11.65" cobra rotors.
So why can't I just use any 94-2004 cobra calipers?
