First, welcome to the forum.
I'm 56 and am also enjoying re-building some of the classic kits I first built back in the 60's.
The Revell Arizona was always one of my favorites.
For me the biggest challenge with photo-etch pieces is making all the bends. Getting the bends on the foredeck hand rails was a challenge for me.
For some of the mast platforms I would suggest scratch-building some replacements rather than cutting the handrails off the kit pieces and adding photo-etch rails back to them.
Other than that, just be patient and take your time.
Good luck,
Mark
