What should I get additionally with your GPIB board (cables...)?
--- Quote End ---
All the headers are standard 0.1" pitch, you'll have to download the schematics, decide which IO you want to use and buy whatever connectors you need.

As I am a beginner and I do not have experience with VHDL, do you have some additional software for configuring GPIB or GPIB2_FPGA.zip is enough?
--- Quote End ---
GPIB_FPGA.zip contains a Quartus project which when compiled can be used to configure the Cyclone III starter kit.
This is a simple example of how the different functional blocks can be interfaced.

In which way Cyclone communicate with PC? Is there a need to use some JTAG emulator as for Texas Instruments microcontrollers or something else?

The example design uses one of the RS232 interfaces on the GPIB.
There's an example Excel spreadsheet/application for download on the projects page which shows how this interface can be driven. This is fairly self explanatory/ reasonably commented.
You could also use the USB slave board which plugs onto the GPIB if you need faster comms.

Is there possibility to get your board with higer resolution of DAC, let say 12-/14-/16-bit (resolution of DACs is much more important than ADCs;
--- Quote End ---
No, although I have used this as a basis for developing a few custom
board for clients. If you wanted a custom board developed (and are
prepared to pay) that could be done.
One solution would be to design your own simple DAC interface board and drive it using the GPIB SPI interfaces.

I have one more question... For my algorithm I need to use some impulses from some flip-flop (that impulses are used for power transistors driving). That impulses are unipolar signals (0 or 3.3V). Can I connect this signal to your GPIB board (GPIO Input or somewhere...) to use as a digital signal which I need for my algorithm, which should go to FPGA?
--- Quote End ---
Yes, the GPIO interfaces (all the interfaces) are 3.3V compatable.
Check out the example design to see how the GPIO inputs are read.
I hope this helps a bit.
