Ignition timing/ TDC on a 94 ford probe GT

I replaced the distributor and forgot to mark or check where everything was positioned before doing so. Do I need to completely reset the timing? Or is there a way to simply just set the timing of the distributor? If I end up having to reset the timing completely can I find TDC by removing the #1 cylinder spark plug and turn the pulley until I feel compression in the #1 cylinder spark plug hole? If so would it be as simple as finding TDC and aligning the rest of the timing marks up? Thanks in advance, ive almost got it up and running again just need a few tips!!!
