Stunning tank and stand you've got there. You can wipe the bubbles off with a algea sponge or your hand or whatever. They usually go away after a day or two.
As for the potted plants, I usually rub the cotton between my hands to loosen it up a bit and then gently pull down from the top. Don't fret if a little bit wants to stay, it won't hurt anything.
I can't wait to see your progress!
