What I am seeing flux. Flux helps the solder adhere to thecopper of the circuit trace. If you would like to completely remove it beforereordering the jack there is a product available called flux remover(64-3324)from your local radio shack. In my experience I have not worried about removingthe flux until I get the board completely finished, then a light spray of theflux remover and a brisk rub with a plastic bristle brush is all that is neededfor cleanup. As far as removing the jack I Highly recommend desolder braid asit removes the old solder. As for you the burning smell you are describing ismore than likely the plastic from the broken jack. using the solder braid willkeep that from happening. Regarding turning the board black this should not happenif you are using a pencil type soldering iron for this job. the old flux will discolorbut the board it's self should not turn "black" * please ensure youonly use rosin core solder and NOT acid core.
