There are redundant {....} here. This is enough:

,*+<2pt>+[blue][F*:white:<10pt>]\txt{First Text}="First_Text",

Also, the ; at the end is not needed,
unless you immediately need the previous POS to be
the start 'p' for an arrow, or 2-point calculation.
A simple , is usually adequate.

This should be OK:

(0,90)*+<5pt>+[F*:blue:<10pt>]i\txt{First Text}="First_Text",
*+<2pt>+[blue][F*:white:<10pt>]\txt{First Text}
%
(0,120)*+<5pt>+[F*:red:<10pt>]i\txt{Second Text}="Second_Text",
*+<2pt>+[red][F*:white:<10pt>]\txt{Second Text},

The 'i' (=invisible) modifier means you get the correct shape,
without actually placing the text twice.

Try above.
It should work just fine.

Sure.
This is all doable.
You'll probably need to use \POS at the start of the expansion
of your user-defined macros.

Hope this helps,
