I really don’t think 1a) is addressed by Eliezer; no offense meant to him, but I don’t think he knows very much about interpretations besides MWI (maybe I’m wrong and he just doesn’t discuss them for some reason?). E.g. AFAICT the transactional interpretation has what people ’round these parts might call an Occamian benefit in that it doesn’t require an additional rule that says “ignore advanced wave solutions to Maxwell’s equations”. In general these Occamian arguments aren’t as strong as they’re made out to be.
If you read Decoherence is Simple while keeping in mind that EY treats decoherence and MWI as synonymous, and ignore the superfluous references to MML, Kolmogorov and Solomonoff, then 1a) is addressed there.
