Yes, this cassette and either chain will be fine. You might not need the cassette depending on the condition of your existing chain, but you won't know until you try. Odds are the chainring is fine. Because they are much larger they wear more slowly than cassette sprockets, and in any case the chain engages many teeth so they're more forgiving of wear.
One note- Unless you've already cleared this with the LBS, don't be surprised if they're less than thrilled about installing stuff bought elsewhere. Most shops feel their labor income is only an adjunct to their sales income, and bristle at installing items they haven't sold, especially in the busier months. Some refuse the work altogether, and others charge higher labor rates than they might otherwise.
If you plan on buying online and having an LBS install, you might respect their sensibilities, and bring them the stuff unpackaged, saying you bought them long ago as spares in case they were to be discontinued, and only now need to use them.
