Is there any evidence that DE were recruited from other houses?  There must be some bad apples in other houses.

The only non-Slytherin DE we really know about is Pettigrew, but that's not to say there aren't others.  From the evidence though it appears that most of the death eaters were Slytherins.
When was the Order formed?  Was there mixture of ages in the Order?  Were some of the OOP people were very young.  Am I correct in thinking that Lupin and Sirus, and possibility even Peter, was in the Order until things went to Hell?  Or was the Order formed after Sirius landed in Azkaban and Peter spent a lot of years as a rat.  What about the Potters?  They were very young to be murdered.  But there are a lot of people too young to die, even in the MW.

I don't know exactly when the original Order would have been formed but guess it was during the first war.  Yes, I'm pretty sure there were a range of ages in the Order.  When Moody showed Harry the picture of the original Order members in book 5, it showed Lupin, Sirius, James and Lily and I think also Pettigrew, as being Order members.  Obviously this would have been before Sirius went to Azkaban.  I think anyone who was of wizarding age and had proved themself would be allowed to join the Order.
Last question.  Did houses always marry within their house?  Or did they look beyond what house they were sorted into.

I think there were most likely marriages outside houses.  There were definitely relationships outside houses (Percy and Penelope, Harry and Cho).  However I think the fact that it would be so much easier to socialise with someone within your own house meant that in general more marriages took place between people who had been in the same house during their school days.  I don't think, though, that every wizard would marry someone within their own house, it's just that on average there appear to be more in-house marriages.
