I have a couple of dumb questions...Does the computer need the stock 5.3 sensors to read its information?

Yes. Most factory LS applications had the computer control the gauges over a network, unlike older GM EFI systems where the gauges had their own, separate sensors.

And on my autometers can I tap into the stock sensors or just go with the ones that autometer suggest, as in their electric oil pressure sending unit etc.

Depends on the gauge.
Temperature? No. You'll need to add a second sending unit.
Oil pressure? Maybe, if Auto Meter's sending unit has the same output curve as the factory sensor. You'll have to ask them.
Speed sensor? Probably OK to split it.
RPM? There's a signal from the computer that you can use, although I believe for some reason you need to set the tach to four cylinder mode to read correctly.
