Except at one location in the schematic of the board, an address is beside each reconfigurable oscillator.

That would be their I2C address probably, not their MAX II address. The MAX II block diagram shows a "Si570 Controller" which can mean anything, eg., a simple PIO block or an I2C controller. Without knowing the address map of that component you cannot program it.

I knew the tcl command for quartus_stp but I can't use it in System Console unless I can add the package "jtag" of quartus_stp in System Console but I don't know how to do.

The script is specific to quartus_stp.

Anyway some Tcl commands from quartus_stp are the same as SLD Commands. I tried the following code in System Console with a bad result:

No, they're not quite. In the script I wrote are the commands used to interrogate the nodes on the Virtual JTAG interface.

set vj 2]
open_service sld $vj
sld_access_ir $vj 2 1000
sld_access_dr $vj 8 1000 0x66
sld_access_ir $vj 1 1000
sld_access_dr $vj 8 1000 0x09
0x66 is the address of the device with which I want to communicate.
9 is the register number indicated by the device designer, which i want to read first.
Which errors did I do in this code?

I doubt this is the correct code.
You need to extract the max2 design located in the examples folder and then review the code. That should provide the information you are missing. You need to know how to program the MAX II controller so that it generates I2C commands to the Si570 device.
A simpler method would be to install the same version of Quartus as the kit distribution and then use their clock control GUI. For example, it looks like there is an 11.1 version on the site now
http://www.altera.com/products/devkits/altera/kit-siv-gx.html If you are running 12.x already and do not want to install an earlier version, then you can install VirtualBox and install an OS (Windows or Linux) and install the older version of Quartus there.
So long as the host is running Windos XP or Linux, then you can connect the USB-Blaster to the Virtual Machine (Windows 7 does not allow this for some reason). You can then use the clock control GUI from within the VM.
