LS70 questions

Hello, I have a pair of LS70s. I love the way they sound (and look).
I have a few questions that I'm hoping someone might be able to answer:
1. While removing one of the woofers, I accidentally pulled up a bit on the rubber surrounds. It didn't tear off, but an inch or so peeled up. I just pushed it back down and I don't think I hear any issues. Did I really mess this up? Should I go in and repair this or think about a new woofer...?
2. What prompted me to remove the woofer was when it was cutting out (more muffled and slightly distorted than fully out). if I touched it (pushed in on it) it came back and was fine for a bit. I took it out of the cabinet and then put it back together assuming it was a loose connection. It was fine for the rest of the night (last time I listened to it). Would you assume it was just a loose connection or is that the sign of a blown woofer?
3. I've read about upgrading the caps, etc. inside of these speakers. Does anyone have a list of components and perhaps a good source to buy them? I'm what you'd call a soldiering/cap noob so I need my hand held for this one.
Thanks!

The rubber surround should be fine. It lifts up to reveal the screws and should go right back in place with no issue.Stan
