complex data requirement

Here is my query:

select Views.VisitorID,
       Views.ViewID,
       Views.ViewDateTime,
       Views.VisitDate,
       Visits.Views,
       ProductID.Product,
       PageID.Page,
       hostID.host
from   Views
       left join Product
         on Views.ViewID = Product.ViewID
       left join ProductID
         on Product.ProductID = ProductID.ProductID
       left join host

       left join hostID
         on host.hostID = hostID.hostID
       inner join PageID
         on Views.PageID = PageID.PageID
       inner join Visits
         on Views.VisitID = Visits.VisitID
where  Visits.Views <= 50
       and visits.firstvisit = 1
       and visitdate = '07 March, 2011'
       and ProductID.Product in ( 'product a', 'product b' )
group  by Views.VisitorID,
          Views.ViewID,
          Views.ViewDateTime,
          Views.VisitDate,
          Visits.Views,
          ProductID.Product,
          PageID.Page,
          hostID.host
order  by Views.VisitorID,Views.ViewID, Views.ViewDateTime  

I am looking for the above records for every visitorID when the very first viewID (there are multiple viewID for each visitorID) is either 'product a' or 'product b'. Can someone help?

Appended below is the data and the expected results are visitorid=1, 2 & 7.

V2 - is the minimum/first view for each visitor on that day. V3 - is the visitors which looked at product A or B on their first view. Then the rest of the query takes those visitors and links them to the rest of the data.
