You are missing the big difference though... K series have an unlocked multiplier allowing for 4.5GHz+ operation.
If you don't plan to overclock, then a E3-1235 is fine.

That blanket statement is not quite correct in all cases. There are other differences as well such as higher operating temperatures, unlocked QPI lanes for multisocket configurations, and other features. There some Xeon models not avaliable in Core versions like the deca-core Westmere-EX. In this case, the E3-1235 has P3000 IGP instead of the 3000 IGP. It uses different drivers for professional support.
It depends on the series.
Also note that Xeons do not always work in every consumer motherboard. They should with a BIOS update but it depends on the mobo.
