Gosh so much stuff on this topic!
First, I had an emergency c-section followed by a VBAC. I would definitely recommend the VBAC but if you do need a c/s for whatever reason, you do recover after a while and you don't do much in the first month anyway. The hardest part for me was not being able to stand or carry baby much (sore abdo muscles), or hang washing (not allowed to stretch!).
I've heard that the reason you're not supposed to drive for the first 6 weeks is because if you slam on the brakes, that action can cause immense pain so that you let go - so therefore you are not so safe a driver! It is so tempting though, I certainly felt "back to normal" within 4 weeks. Also, one side effect of c/s is that your scar tissue can rupture in a subsequent labour, but that's not a high probability and you will be referred to an obstetrician for all those stats at 6 months anyway.
As for nakedness, I'm quite a private person too and even after going half-way through labour with the first baby, I was kinda freaking out about it for the second labour. But my midwives were very discreet and by the time you're up to pushing it really is no issue to you at all. Don't worry, they're there to watch the baby, and of course to see that you don't tear.
As for pain relief, I would suggest to anyone going into labour that they keep open-minded on it. Work out what you want to do for light (e.g. gas) or heavy (e.g. epidural) pain relief and just go with what you are feeling. I had an epidural with the second one, but I won't be having that again because I felt it was more distracting than helpful. Fingers crossed for not too much pain this time around....
