You should take a micrometer and measure things... and try some plastigauge...
There are two options for the Main bearings on the 1.6, there
is .10" (.50mm) o/s and there is std.
I'm assuming std stands for standard and not what we learned
in health class
I'm confused as to which one i should get.

You only want the .50mm if the crank journals have been turned.

Taking the head off will not make it any easier to get to the main bearings (it will actually create a lot more work for you). Getting the oil pan off is the only way to get this done. It will require lifting the engine part-way out of the car, so pulling it completely is not unreasonable.

Take it out and turn it upside down on a motor stand to do it.
MUCH easier. Less likely to damage a bearing since you don't have to hold the crank up while trying to fasten bearing caps in place...
