Elbow grease! I recommend leveling up to at least 45. It will make it easier to cruise on through to the end of the game. Make sure you have as much invested in HP as you feel comfortable without squandering your CP. it should be a healthy balance between the two, with sleights thrown in as seasoning, not the main course. Find what works best for you, but try and get as much defensive buffer in your green health bar as possible, and strong sleights to whip Riku into shape. May I recommend Oogie Boogie? Regen is an indispensable ability. Good Luck!
Since you must have had a GameShark to be Riku, I'm not so sure. I haven't gotten the Gameshark or heard any strategies for that.
After you defeat the Replica Riku, somewhere in that room is a Treasure Chest, and you'll get the Oblivion.
Yes. In Kingdom Hearts: Chain of Memories, Vexen made Replica Riku was as a plan B when his initial plan of recruiting the real Riku didn't work. While in Castle Oblivion, Vexen created a spitting image of Riku infused with Riku's memories, but the memory was altered and manipulated by Namine in order to further fault Sora's plans. This plan failed when Namine told Replica Riku the truth of his existence.
