I've got little money but just stumbled on this and had to pick it up. It gets me off my conversion and I'll start commuting on it with longer training rides on the way home (bike trail) and I hope to hit the Encino Velodrome soon. I know they have rental bikes but I couldn't resist it when it came up locally.

So here's my question:

I'm 5'9" and ride a 54cm frame with 100 stem so I'm hoping this 53cm will do fine with a longer stem and a seatpost adjustment.
I have 170 cranks and basic road bars to use.

When setting up fitment I use KOPS as a basis, then use the Reach rule of thumb: bars line up with the front axle when seated on the hoods. Is this the same type of basic I should be using when the wheelbase is shorter on a track frame? I assume I should size it to an aggressive position when in the drops? or just try to match my road setup?

Moving to SSFG from Track Racing.

This forum is for folks training/racing at the velodrome. You have only expressed interest in doing so in the distant future. Get commuter advice from SSFG.

Move to bike fitting forum?

Start riding At the track with a rental bike.
This gets you riding at the track sooner and you can ask around to see if your new acquisition is apropos.
The 53 cm bike will be fine for fit, just set the bars slightly lower.
Get some 165mm cranks. The 170s you have may give you pedal strike on the track.
Or, they could be okay...once again, ask around at the track.

I'll set it up like my road bike, ride like hell and get my beginner course started.

Have you read that place? There should be a warning, 'suspend all reality now'. At our worst we offer better advice than what passes for wisdom there, surely the biggest mistake the admins have made.

Wow, I should check it out some time.
