The real issue is whether or not they will remove the Block II's from service, and how many of the previous blocks that would be.
Since block III's have an 8 year lifespan after which they have to go through overhaul and replacement of certain key parts (no reason to believe block IIs have a longer lifespan) i doubt US intends to spend money on keeping block IIIs operational after their life expectancy has ended. What is gonna happen is what happened in first gulf war, older cruise missiles would be first to be used in any potential future war ( attack on iran, for example) while there's still some guarantee that they'll work.
Your figure of 2200 tomahawks, however, doesn't really match the numbers mentioned in USN institute article. And since block 3 production has ended years ago and block 4 has started up just recently - numbers should be pretty finite. Since 1998 1400 tomahawks have been spent. Actually before war in iraq started, after afghanistan, US has something like 2000 tomahawks left. spending at least 725 by april 2003 (figure of 800 that i've seen thrown around as final iraq war figure seems reasonable then) it'd mean us today has at its disposal something like 1200 tomahawks. Perhaps the 2200 figure you mentioned is refering to total number of all versions, even the old, bunkered antiship versions?
And yes, i agree tomahawks can be pretty useful, but only when they're a part of bigger and more complete attacking force. What's the point if you use a tomahawk to destroay a radar station if you dont follow up with an air strike w jdams or whatever to destroy the planes on the ground or whatever else? If you stop with just that first tomahawk, the radar station will be replaced/repaired eventually.
