First of all, thank you for putting this tutorial together. It's very well written and it's been a great resource.

Unfortunately for me, I'm having some issues getting the jtag-to-Avalon-MM bridge to work on a Altera Stratix IV dev board, 530 edition. I'm able to get everything to compile, and everything passes in simulation. However, after programming the FPGA, and using quartus_stp to issue commands from Figure 15, I get the following error:tcl> jtag_write 0 0 0x23
Error: incorrect number of response bytes!
Everything up to that point works. The jtag_open, jtag_print_hub_info and jtag_print_node_info all produce the expected result.
Do you have any ideas what could be going on here?

Any reason why you're using quartus_stp? If you are just using the command line, then SystemConsole works fine. I was using it today on the 230K version of the same board.
I won't be at work tomorrow, but I'll see if I can find the issue with quartus_stp on Friday.
For now, why not try using SystemConsole - look at the jtag_cmds_sc.tcl scripts in the boards area.
Which version of Quartus are you using?
Cheers,
