Oh good! I'm so glad your dh is supportive, and you are headed toward a good year of homeschooling!

As far as the RA's go, I'd follow the plans in the LHFHG for the remaining 2 Thorton Burgess books that you have not done first. Then, I'd finish out the year with your Beyond RA's and those follow-up skills. The following year, you can go through the Beyond RA skills again with the other book set. This will streamline the books you are needing this year, give some practice in the easier skills first, and give your kiddos 2 solid years of building reading comprehension, listening, and narration skills prior to beginning BHFHG.
In Christ,
