Hello Pigboat,
I am no expert, especially with things like cabinet construction/refurbishing and passive crossovers, and I don't own any of these speakers.
I also have no daughter, so take my opinions with a grain of salt, but here is what I would gather from what I read around here among the years.

5 xover? Rebuilding? Removing pots from system? Active?
6 connectors?
1: leave it alone unless you hear or see problems
2: no need unless a problem occurs, and probably not beneficial without a crossover modification (measurement, simulation, etc.). If the 035 was cited as a replacement part by JBL that probably just indicates that the original driver was NLA at the time and the 035 was a sub optimal solution (NLA as well these days)
3: No
4: No
5: rebuilding is probably overkill but you could replace the caps and pots. Zilch posts come to mind for more info
6: you can clean them if they are oxidised, and replace them if you need to install bigger wires and/or different types of connectors

Any thoughts ?
Help with L15 Refurbish
1) Cabinets, dampening, leave it, add to it, remove/replace it ????
2) 034 Tweeter has lost it's silver paint/aluminum? covering, works, replace, repaint ??
3) Crossover, Cap replacement suggestions
Change inductors to air ?
Change resistors ?
Build external "charged xover" ?
Change xover frequency to 3K(read somewhere?)
4) Change connectors
And anything that will help with project.
Not worried about keeping original.
Just having FUN.
Pair of 4406's after these.
1: leave it alone
2: any covering would probably alter the weight and overall behavior more than the original one, or its absence
3:
caps: any good cap that fits and is in your budget. Parts express has all the majors brands, along with opinions
inductors: no reason to change (does not wear), and changing them would alter resistance and change xover behavior
resistors: no reason to change (does not wear)
charge coupled: probably overkill, but member 4313B did it (and posted a dedicated thread about it) with similar sized speakers, apparently with great success.
change xover fc: why?
4: parts express
Any of the speakers in your list would probably call for the same answers.
All the info you seem to look for is already on these forums, you just need to search for it (possibly using google with a
site:audioheritage.org query), and discover new things along the way
hope this helps
