Don't stop. Read The Talisman after you're through with BH, but don't put too much time in between - you'll understand BH somewhat better, and I think you'll like the Talisman more, too; but this retroactive understanding is best done when as little time as possible has elapsed.
Then you can read BH again.
And again... in any order you like.
Anyway, it is not a one-time read, so the order doesn't really matter.
