If I were in your shoes I would try & buy the right tool for the job as Steve has suggested. Steve stated that PS might be the tool but if I was in your shoes and was doing this a lot in either a professional or semi way then Adobe Premiere Pro would be the tool to use. If however you were only doing this occasionally then Adobe Elements does nearly the same as PS does and it is a lot cheaper to buy. Don't just stop looking at Adobe products as there are lots more programmes which will suit your needs so do a bit of research download a few and see which you prefer.

To answer your first question the Intuuos works really well with the Freehand Tool as I have gone from Graphire up to Intuos but still don't use it enough as it is really better suited for a bitmap programme than a vector one!
