1. This will happen starting on Tuesday 8pm, after Steem-Engine hardforks to allow increasing of decimal precision.
2. Yes, you just haven't been upvoted by someone with a stake high enough to collect at least 1 PAL. That shouldn't be a problem after the fractional payouts (see above).
3. Yes, 7 days.
4. About 3,300 PAL at some point, but maybe numbers have changed a bit in between.
5. Yes, same as on Steem about the VP recovery rate. But it is likely you will vote more Steem posts in general than Palnet posts, which will make your VP on Steem drop at a higher rate than on PalNet. That will be fixed in the future. Additionally, Palnet has a separate downvote pool which allows anyone to give 1 free downvote every day. Any subsequent downvote costs VP. All these downvotes cost VP on Steem for now, but after HF21 there will probably be a separate downvote pool on Steem too.
6. No, rewards on Steem or on PalNet have no relation to RCs. You do need RCs to cast a vote though.
7. Not yet, there will be a PalWorld (the SteemWorld for PalNet) soon, I read.
8. It's not VP which is delegated, it's the stake. Which, it's true, affects the VP. This will be available after the hardfork on Tuesday.
9. This will again be 'fixed' in next week's hardfork, I believe.

I hope I answered your questions. If not let me know.
