Make sure you have a nice gigE switch as well as jumbo frames enabled on BOTH the switch and ESX servers. And yes Foundry rocks for iSCSI :)
To your specific question of what kind of switch should you use, believe it or not I don't think there is a HCL for Ethernet switches from Netapp, but Foundry and Cisco will be sure bets. Make sure its gigE, managed, and supports jumbo frames.
Perhaps a good question to ask is what kind of performance issues are you having? IOPS, throughput, or instability? A FAS200 wouldn't be the first platform I'd think of when designing an ERP infrastructure too...

Dedicated switch.
Whats the make/model ?
I'm not a SAN or Network guru but I have heard performance can suffer if you have substandard switches or incorrect configuration.
What performance do you get when you do a big file copy ? On the SAN and the ESX servers to see where the bottlekneck is.
