I do the same - walking even short distances is just too uncomfortable with typical road shoes !
I use my shoes/pedals interchangably without difficulty - dunno if that holds for *all* SPD products. The LBS where you purchase such things (or, the customer support help line at Performance/Nashbar) could tell you for your specific models.
Pedal choice depends on how aggressive your touring is, I think - i.e., durability is a greater issue in the Australian outback than in most of the US. I've never bought "tour-specific" pedals - guess I always figured climbing is climbing, with or w/o added baggage....
