Some things to note item wise using information from Tommi's Page.
Trang Oul's armor actually equates to the same run/walk speed as stealth by itself. 40% r/w = +1.24 and it being heavy armor = -0.40 so you get 0.84 which is what 25% r/w equals. Note though that with the diminishing returns you get from item r/w speeds I think in the long run stealth would end up being faster. So I agree with your choice there. : )
As to shields, I don't know of any off hand that give run walk. You could go with a lidless though. The +1 to skills would give you more run/walk if you use a char with skill r/w. It is a light shield as well so no r/w penalty there. Also using both it and stealth would give you 45% cast rate. So you could consider using a character that would take advantage of having cast rate and run walk.
