I have to say no on both counts, firstly there is no archaeological evidence for smoking amongst the vikings. That is asides the possiblity of 'communal smoking' mentioned above. I collect English translations of the Icelandic Sagas (I have 20+) and to the best of my memory there are no references to smoking - plenty of drinking, fighting, wenching etc but no smoking.
As John has said the first pipes would likely have appeared in Ireland c.1600. These pipes were of clay with particularly small bowls - an indication of the scarcity of tobacco at this time - which were shaped tapered at both ends and at a 45 degree angle to the stem. The 'heel' at the base of the bowl was only embryonic at this stage.
Below is a typology of these early clay-pipes from the book 'Marinarkeologi' by the Swedish author Catharina Ingelman-Sundberg:
Hope this helps.
PS It so happens that I collect clay-pipes too...
