Replies to numbered points:
1 - Its True Name was
"The War For Slaveholders' Privileges."
2 - "intended" not "expected" to fight there,
but note that Lee did take it into Maryland in 1862,
and into Pennsylvania in 1863.
Still, this has the Best Support of all these points.
3 - The Army of Tennessee was in Georgia,
for all the time that Joe Johnston commanded it.
4 - McPherson and Sherman commanded the
(Union) Army of the Tennessee, which Grant had
formed there and taken to Vicksburg, Miss.
It was dependent on the Tennessee River for supplies,
but was in Georgia during McPherson's tenure.
NOTE: it did recruit some soldiers in Mississippi.
Almost all of them were black.
The Union Army of the Mississippi was Pope's outfit.

a Confederate General (R. E. Lee) commanded the
2 -
Army of Northern Virginia (named so,
as that was where it expected to engage in combat).
Another Confederate General (J. E. Johnston)
3 - was commander of the
Army of Tennessee,
which held off a flanking attack by Union General
4 - James McPherson's
Army of the Mississippi (I can guarantee it's soldiers didn't
come from Mississippi
) which happened to be
Union General W. T. Sherman's former command.
