Typical Oil Pressue
I noticed my oil pressure guage can read around 3/4 of the way to it's maximum range. Especially when the car is warming up. Is this typical? I don't want to blow any seals out.

When the car is not warmed up it runs higher. Once at operating temps I would say 40-45 is normal. Note that when you drive it harder the oil pressure rockets up... Which is normal.
EDIT: I wouldn't worry about blowing any seals anyways as I don't trust these oil pressure gauges anyways. They have a tendency of breaking.

When I get on it... Oil pressure on the DIC says 77 psi. The guy I bought the car from said he installed a LS3 oil pump. Do those tend to run at a higher pressure? At idle the pressure is around 50psi.

50 psi @ idle? Sounds like a bad sensor to me. Mine is 30 @ idle and 62 psi @ 6k rpms and I have a ported LS6 pump.

Accessory belts and also fuel injectors can cause ticking so don't panic needlessly.

i just noticed this last night...
mine idles at around 35-40 psi, about 40-45 psi under normal cruising around, and if i get on it will get up to 65-70 psi... is that really normal? i feel like i would have noticed that sooner?

The LS1 only needs 8 psi oil pressure at idle. Having said that, I switched my oil filter from GM DELCO UPF-44 to a WIX or NAPA GOLD (same filter) and my cold oil pressure increased 10-15 psi (the oil sensor is AFTER the oil filter so this is an increase in flow). An oil analysis showed no difference.
