Yeah, as much as I'd love to snag that 240mm off you, 90/150/240 is a great set of focal lengths and those are regarded as among the best field lenses ever made (small but sharp). So it's worth trying everything out and seeing what you think. Sounds like a great kit, put together by someone who knew what he was doing.
Load some velvia 50 up if you have a light table. It's cool how good it looks at 4x5 and slides are instantly gratifying (and then the frustration of getting an acceptable print sets in...). One accessory I might recommend is a basic changing bag ($20 new). I lost mine a couple days ago and now I realize how much I need it. I guess this isn't an issue if you have a darkroom so much.
