Re: No timing mark on the oil pump
It's an aftermarket pump. The keyway in the crank should point straight up at TDC, use that for a reference. It's not ideal, but if you have no timing mark there's not much else you can do short of replacing the oil pump.
Btw. the end of the crank looks chipped or otherwise messed up. Also, that oil pan gasket is torn and was probably overtightened when installed, there's also a sealant where it shouldn't be.

Yea, just use the woodruff key as a reference. You could double check with the "screwdriver down the spark plug hole" trick.
If you really wanna be considerate to the next guy working on the car (which might still be you lol) you can take a dremel or something and make your own mark on the pump when you're certain it's TDC.

Re: No timing mark on the oil pump
That oil pan is torqued *way* too tight (and unevenly), which is probably why the gasket is split under the oil pump.
Someone probably tightened it up when it leaked due to all that sealant preventing a good seal.

Damn, yea... I didn't notice that. I think those bolts only go on at something like 9lb-ft. and in the proper sequence. That thing looks crushed down, hard. At least in the pic.

Re: No timing mark on the oil pump
When you go to reassemble, and have the crank pulley back on, just line up the TDC mark on the crank pulley with the notch/pointer on the timing cover. That way, it'll eliminate all doubt. From the pic you posted, though, it looks like you're pretty close if not dead on.
