The most important is not having fear to command tools like modelsim, is such a fear, that disables you to think, even tough quartus is for two years old children compared to modelsim, it is terribly difficult.

Using the tools becomes much simpler if you learn how to use the Tcl scripting language. The nice thing about scripts is you can write comments in them to remind yourself why you did things. Using the GUI is not as useful, as if you do not use the tools for a while, you forget how to use it. Look at the modelsim_example.zip file I referred you to earlier, and look at this tutorial:
http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial It has both Quartus and Modelsim Tcl scripts.
