I plan to get new cats for my 2001 4.0L. Flowmaster has all 3 for 260 but it is only for 2004-2006. Can anyone recommend cats the only systems I could find for a 2001 were close to 600 when added together.
 
Looks like your estimate is spot on for what I could find. $600 for parts+tax+shipping is what my calculator shows for a Walker OEM setup, which I think is the least expensive on RockAuto.

I noticed that Eastern Catalytic has all 3 cats for about 350 which is far cheaper than buying them separate. If I moved the hanger would I be able to run the later model cats on my 2001.

You should be able to, yes.
