If you look at the Miniprog3 user manual you will see the 5 pin SWD interface
and 10 pin JTAG interface connections.
Yes, that helps. There is a section in the manual that specifically states what is needed.
Glad we could help.
Just want to add, you will need bulk and de-coupling caps on power supply pins. You can get recommneded cap values from power supply figure in PSoC3 device datasheet.
