You should always stick with a real King James Bible. No words changes or stuff like that. The Bible says in Matthew 4:4 that we live by

Now, if the tips help you, I don't see anything wrond with using them.

The best way to read God's Word, is by simply reading God's Word, and try to keep man's word out of it.
I'm not saying there's anything wrong with having a Bible with notes, I'm just saying it's best to stay away from the notes, and certainly stay away from "updated" versions that claim to be King James but really aren't
