I'm not sure I would use the standard Muntons on the higher strength beers you're planning. I've not used it on anything above about 5.5% so I may be wrong but it might leave the FG too high. If you want one yeast for all four beers, I'd personally either go for S04 or Nottingham/Windsor, though I've never done the latter. Muntons Standard will get you closest to a Fullers bitter in my experience. Not really close, but decent, it's given me some nice lower strength English ales.
