Not sure what you need, but
Xilinx Design Tools and
boards could be a start. Xilinx states that ISE works with Win and RHLE, though it apparently run ok in Slack 12 through Wine (didn't tried to run the RHLE in Slack).
Or try Altera at
http://www.altera.com/products/software/sfw-index.jsp
There are boards and kits with the HW built and ready for testing and programming.
At
OpenCores you find many user built cores for common needs, or take a look at the
VHDL-Cookbook.pdf.
