Hi,

Well there are 13 6500 models listed so without more knowledge of your network requirements your best bet is to refer to the link to the download page.  There you can read the specific release notes so you can make an informed decision.  For example you can download the latest software for a Cisco Catalyst 6000 Series Multilayer Switch Feature Card 3 (MSFC3) (122-18.SXF17b) here.

Here are corresponding links to 4503 and an example. (15.0.2-SG5)

And lastly the latest FWSM is 3.2(24).

Hope this helps.
