Keep it in RGB. You’re going to send them a flattened RGB JPEG, meaning your fonts will be rasterized and flattened into the background.

You can keep it layered in Photoshop (or ID or IL, wherever you’re designing), for ease of editing.

Please take some time looking at book covers in the Amazon Kindle store so you can see what stands out, what works and what doesn’t. Typically you use very little text, or text that’s there is larger than what you’d use for print. Also be sure not to mention price or any marketing/selling info at all.

Amazon has lots of on-line and PDF-based resources for creating Kindle ebooks. Here’s the page with their instructions for covers:
