Is 1-(methylethoxy)-2-methylpropane another correct/acceptable way to write 2-isopropoxy-2-methylpropane?

Of course it is, you can always use systematic naming :)

Is tert-butane the same as methyl-propane?

No, tert-butane is not a thing. See picture for explanation.

On problem set 2 number 5, why wouldn't you use E and Z notation?

Better question when would you use E and Z notation for cyclo-molecules?

For 8-membered rings and larger.

Is there a similar rule for using E and Z describing 8 membered ring structures but in branched and non-ring structures?

What does it mean for a ring to be 8 membered?

For Practice Problems 1, for 2-isopropoxy-2-methylpropane why would it not be 2-isopropoxy-1,1-dimethylethane

I believe an 8 membered ring means cyclooctane. Possible larger rings include cyclononane and cyclodecane (if they're C-C single bond rings) because we are only expected to know up to the prefix for 10 members.
