If I setup my connections as I have done in the jpeg that I have attached will:
- USB-Blaster Jtag programmer power up correctly?
- The signals from the USB-Blaster program the FPGA correctly?

Your pin 8 is wrong.
Look at the USB-Blaster user guide, page 18 and in Table 2-2 on p20
http://www.altera.com/literature/ug/ug_usb_blstr.pdf Pin 8 in your schematic should be a no connect.
You should really re-number your schematic symbol to use the standard pin numbering convention of odd down one side and even down the other. Note that this is how the pin numbers are shown in Table 2-2 of the user guide. You have mapped them correctly in your schematic (with the exception of pin 8), but it could be confusing for users of your design.
The FPGA will tri-state TDO, so it will float. Add a pull-up to TDO so that the input to the USB-Blaster is always at a valid logic level.
