1. Can't help.
2+3. To beat Riku you need a good deck. To get a good deck, you need to synthesize rooms with Moogle cards and buy good cards, not to mention smash every barrel, tree, jump on every pile of leaves. Get at least 3 0's without selling them. Remove all the cards from your deck and add the 0's. This way, they will be the first card in your deck. Then put all your highest ranking cards, such as 9's, next into your deck. The next thing you'll want is 3 cure cards. MAKE SURE THESE ARE HIGH LEVEL CURE CARDS, OR ELSE RIKU WILL SIMPLY BREAK IT!!! But this depends on the next cards you add. If you choose cage parasite as your enemy card, forget the capital letters. But the two enemy cards I suggest are Jafar and Vexen. I might have spelled that wrong. Now that you have your deck set, I'll tell you how to use it. At the beginning of the battle, shift the cards to your nearest 9. When Riku uses his teleporting attack, switch your card to zero, which should be to the left of your 9's/strong cards. Use it and it will break Riku's attack. When you are low on health and out of cure cards, use your Vexen enemy card. When you have his health down to half of green, no blue in it, use the Jafar card so you can break his attacks with any card. This is what you should do to beat Riku.
4. For Pete's sake! Keep killing heartless, a green is bound to show up. It's annoying that is won't show up a lot, trust me, I know, but there's no trick to getting green door cards! Hope I helped.
