You fly via Stansted (I think - schumi'll correct me ) But they may be seasonal flights. Check out Atlantic Airways' wikipedia page, which may have more info. Alternatively, I think there's year-round flights via Aberdeen, Bergen or Copenhagen. Or get the boat, which takes longer. Flights can be diverted to Bergen because of fog. Bergen's a lovely spot too though, so no massive loss if you end up there for a break instead.
Lovely place. May get a bit boring if you're not into walking and scenery and the likes. Mykines is supposed to be lovely (probably won't get there in the weather in March), Klaksvík looks stunning, Café Natúr in Tórshavn is good for a few beers (pretty much legendary pub after the 2005 away game), Eidi and Gjogv are nice spots, the cliff tours from Vestmenna are good. A lot of stuff mayn't be running in March though; again, depends on the weather. Local transport is by bus or helicopter - the latter looks fun!
Basically, for stuff to do, google photos of the Faroes. You'll get numerous stunning landscape photos. If you like what you see, go. If you want more, don't bother. Here's a good start; here's google images.
