The seatpost is 25.0mm diameter. A little tougher to find than the norm for steel frames, but still out there. However, it's held in place by a set screw on the back, so a genuine Vitus seatpost is needed (I think). I bet Euro-Asia Imports still has then (see that thread for my comments).
As above, it's probably standard English bottom bracket and headset, but a good bike shop can verify that for you. If it's not, French and Italian BB's are still out there.
