Interesting. I am sure the bottom of the barrel will make a good start, if nothing else it will make me appreciate a nicer model if I should upgrade some day. This kit comes with a roll film back, which would make the 105 more acceptable with the 6x7 crop. When you say too wide for 4x5, does this mean vignetting? Can you combat this by stopping down? There is so much I want to learn, getting my hands on a kit is step one...I really appreciate all the feedback!
The 4x5" format requires a lens that will have an image circle around 160mm. If you purchase a lens with an image circle at F22 of 160mm or bigger, it should be alright for the 4x5" (9x12cm) format.
Vignetting is one way of saying there isn't enough coverage, but to my way of thinking it means if I move the lens board up or down more than a couple of millimetres, I run out of coverage and thereby vignette the film.
You need to do a bit of a web search about lens coverage to get a handle on what you will need, doing this will give you far more of an idea of what is what and what you will need. You will be far more relaxed and secure after acquiring this knowledge. You are of course acquiring this knowledge now, but you need to slow down a bit and learn a bit more by reading as much stuff as you can cram into your brain, then sleep on it so your brain absorbs more and therefore you know more.
You'll get there.

Ps: I suggest you search on the web for the image circle of the Zeiss 105mm lens.
PPs: almost always image circle is quoted when the lens is stopped down to f/22, if you shoot at a wider aperture, say f/5.6, you may fine your image circle is smaller and you will indeed suffer from vignetting if you are on the limit.
