Your evening for a 4:30 AM start

Times worked back from an 8:45 PM bedtime. A 4:30 AM start makes for an early night. If 8:45 PM is hard to reach, 10:15 PM still gives you 4 full cycles, fine now and then.

How much sleep do I get if I go to bed at 9:00 PM?

About 7 hours 15 minutes once you're asleep. That ends partway through your fifth cycle, so 4:30 may feel rough. 8:45 PM or 10:15 PM line up better.

What if I can't fall asleep by 8:45 PM?

Aim for 10:15 PM rather than a time in between. Four full cycles (6 hours) often feels better than 7 hours that ends mid-cycle. Just don't make it a habit: most adults need 7 hours or more.

What if I hit snooze at 4:30?

Each snooze buys a few minutes of light, broken sleep, not real rest, and the alarm keeps pulling you out of it. Get up on the first alarm, or set it for when you really need to be up.
