sounds like a nice recipe :)
i too had issues w/ 1 or 2 bridges on just a tqfp-32 package and also a couple legs that didn't make contact, i think the solder paste i used needed more flux. to fix it i laid a whole solder line over the pins and then used solder braid to clean it off - worked wonders w/ no bridges and all the legs made contact - perfect.
