Current end of life info can be found at http://www.brocade.com/services-support/eol-product-support/index.page - however the the switches you have listed are too old to be on that page.
I am sure the 2402CF and 4802CF are end of support and if the FLS's are not then they will be as the end of sale date for these was a very long time ago.

You are due for an upgrade. The 2402 and 4802 are long gone and the FLS family are end of sale and will be gone in the next year or two as well.
What's the application? The new ICX platforms (6450/6610) could be something you want to look at as replacements.
If you want to keep that old gear running ebay will most likely be one your only options. Definitely get some shelf spares.
