Yes, you should.
I am already doing this 2nd time.
This is not the first time you missed a step......
Make sure you check (double check) all the steps you do. Just about all the steps are done for a specific reason and are therefor important.
Your host OS is needed to build chapter 5.
Chapter 5 creates a base on which you build the final LFS system (chapter 6/7), when you start with chapter 6 your host OS is not needed anymore.
If, after correctly building chapter 5, you might want to consider creating a backup/tarball (see chap 5.32 last part). If something goes wrong later on, you can restore this backup/tarball and start from the beginning of chapter 6 again (which safes you the trouble of having to re-install chapter 5). But this is with the assumption that chapter 5 was build correctly!
Hope this helps.
