You don't need to take the subway to get from Penn Station to 28th Street and 8th Avenue (which is in the Chelsea neighborhood, by the way, not in Greenwich Village or Greenwich Connecticut). Penn Station is at 34th Street between 8th and 7th Avenues. So you can just walk there.
E-train north.
They are both on the New York Subway system, but you'll have to transfer. The best way to get from Grand Central Station to Penn Station is to take the "S" train to Times Square and then take the "1", "2", or "3" trains heading Downtown. The 34th Street stop is by Penn Station. The subway map calls the A, C, E 34th Street stop the Penn Station stop, but the 1, 2, 3 34th Street stop is just as close; walking from the "S" train to the A, C, or E would take awhile since there is a lengthy walk from the S stop on 7th Avenue to the A, C, E stop on 8th Avenue. It's not worth that.
You don't have to take the subway; it's 2 blocks. Penn Station is at 34th Street between 8th and 7th Avenues, and 520 8th Avenue is between 36th and 37th Streets.
