I would like to run the tanabe nfs but i know i should change the shocks i was wondering if anyone has the mazdaspeed shocks and how they felt i know there is better part out there but if i get the mazda ones i can get them covered under my factory warranty

Yep MS is covered under warrenty but MS products are not that great and way over priced.

I switched out my struts when I installed the full MS suspension. The springs are very stiff, and the MS strut that is matched for them is softer than the stock strut. Check the "springs, springs, springs" thread to see how your Tanabe NFS spring matches to the OEM/stock spring rate. If they are close, then you would be fine with keeping the stock/OEM strut.

does anyone know how many miles you are supposed to get on the factory shocks before you are recommended to replace them?

I switched out the stock struts for the mazdaspeed while I had my H&Rs on because the ride was too bouncy. It cleared that problem right up. I now have them on with the Espelir springs and the ride feels great.

Not true.... Fastmike put a set on a shock dyno and this is what they found for MS VS stock:

"Rear rebound runs about 75% stiffer.
Rear compression is actually softer by 15% or so once 3 in/sec is hit but the same as stock before that speed.
Front rebound and compression is about 25% stiffer."

That's a complete surprise, but then again, my method of testing was not as accurate as a shock dyno....still would like to go stiffer for the track though. For street, the MS setup is perfect.

The MS shocks are pretty stiff, I know I have them. I would get some adjustables if your not sure how to balance the suspension with your springs.

Those springs are a lot shorter than OE, but not much stiffer. IMO you need shorter shocks (than OE) to keep off the bumpstops, at least 1/2 the ride height drop shorter body. The Koni shocks meet this requirement, not sure about MS
