You can choose between
option 1: Airport link (BKK to Makkasan) => MRT (Phetchaburi to Sukhumvit) => BTS (Asok to Phrom Phong)
and
option 2: Airport link (BKK to Phaya Thai) => BTS (Phaya Thai to Phrom Phong)
They are planing to have a common card (Mangmoon card) for BTS, MRT and Airport link. But at the moment you need to buy 3 tickets for option 1 and 2 tickets for option 2.
In addition to the time for buying tickets, changing between Airport link, MRT or BTS will take some minutes too.
About saving time: It depends on how bad the traffic jam is, how fast/experienced you are in changing stations and buying tickets and maybe how many pieces of luggage you have to carry. I think, most of the time option 1 will be the fastest one, followed by option 2 and the slowest will be the taxi. But if there is no traffic and no waiting time to get a taxi at the airport, it's also possible, that the taxi is the fastest.
I use to take a taxi for Hilton Sukhumvit and Conrad, but for i. e. Interkontinental or Siam Kempinski I take Airport link and BTS from time to time.
