I think John and 2F/2Fgave you good advice.
I might add that, for me, 210mm is a bit on the long side to be a good first lens.
Another good book on the subject of large format photography is View camera technique by Leslie Stroebel. It can usually be found for very little money on the used market.
Another advice is to check out the articles on http://www.largeformatphotography.info/
