SDS is a solid, so a 10% solution will be 10% weight of SDS in water, 10g per 100ml The weights and volumes aren't critical. Are you a student or working in a lab? What background do you have?

If you want to get the gold out, simply add more water to dilute the binder, the gold will then fall the bottom of the container and you can simply pour off the water.

Do you REALLY need to sequence this protein or just get an N-terminal sequence done - very different proposition? An N-term sequence will give you enough info to get a DNA primer done and to search the databases. It is far easier and faster to sequence DNA than protein. Don't forget that to do a full protein sequence you will need a large amount of material.
