The reason I say black bag and shoes is that it would be difficult to get a pair of gold or silver that would not end up making you look like tinman! You could go for nude but I always think they are a bit meh!
If you were daring and depend on the tone of gold a pair of cobalt blue would be stunning - but I would still play it safe and go for black xx
Sorry but I don't think the pink shoes will go. They might go if the dress was silver but they will clash with gold because gold is a yellow based colour and pink isn't. You're a bit limited really - you would have to go with silver, gold or black IMO
