My suggestion doesn't deal with the big picture, but some minor
tweaking...  The redundant setting of tags and categories is going to
be a real pain in the long run and will also be a source of errors if
an editor updates one but not the other.

(1) I think the categories can be set a single time like this:

(:if false:)
Categories:[[!Cat1]], [[!Cat2]]
(:ifend:)

(2) I'm not familiar with the (:tags ...:) markup, but I think you
could define a PTV pattern ($PageTextVarPatterns) which would read the
(:tags ...:) markup (just hardcoding the "tags" into the pattern).
(You may have to adjust the order of the (:tags ...:) rule to make
sure it runs earlier than the rule that removes the hidden PTV.)

(3) This would be your footer:

||border=0 width=100%
||'''Tags:''' {*$:tags} || '''Categories:''' {*$:Categories} ||

If that works then you should have a single definition of categories
and a single def of tags and the {*$:Tags} should be solved.

Whether there is a better "big picture" solution I will leave up to
others.  But hopefully this will fine tune some things to some degree
on the existing solution...
