you can access the EPM3256A pinout description for the PQFP208 package.
You will obviously need to connect the GND, VCC, VCCIO pins to the correct power supply nodes per the datasheet.
The USB Blaster needs to connect to GND, VCC, and of course TDI, TDO, TMS, and TCK.
The USB Blaster datasheet gives the pinout of its 10pin connector.
As to reading the contents of the chip (meaning the existing program in it, if any) the currently available versions of Quartus that support this device (like 13.0sp1 or 13.1) do not support this capability. You can blank check, program, and verify, but not read back an existing program. Altera removed that function from those versions (why I don't know, they never really said). There might be earlier versions of Quartus prior to 13 that allow that capability but I don't have any first hand knowledge of that. I never needed or used that function.
As to third party programmers, the xeltek website lists this programmer as supporting that device:
https://www.xeltek.com/isp-programmers/in-system-programmers-superpro-is01/
you can go to their device support search page:
https://www.xeltek-cn.com/devsearch/search.html?lang=en-us
enter your part number and that programmer pops up as relevant.
