Yeah. I would also recommend the Cyberiad and Star Diaries to start. Both are slightly interconnected short story collections with a lot of humor. The Futurological Congress is a complete (but short) novel and the first follow-up to the Star Diaries, it's also a good place to start.

For Solaris (a serious novel) I would recommend the new Kindle translation, if you are reading in English. The old one was a retranslation from French for some reason.
