Don't worry about the not reading part. We don't either. We just make answers up
If your phone is currently functioning, do a nandroid backup. You have one from before you moved to this rom too. I tend to name them by rom name and date to keep track of them and know which ones I can delete down the road. From there you can install a new kernel and if it doesn't work for you you can just nandroid restore and try a different one. That's the beauty of having backups. There isn't much fear of screwing up.
I don't know which kernel is the best one for you. There are a bunch out there you can try until you are happy with the results.
