I've mentioned this before on other threads, but what I think is a really good idea if you can do it, is take her for lunch/dinner at the Filipino Restaurant in Earl's Court about 2-3 weeks after she arrives.
It helped my missus's cravings and missing of home, a little bit of time to chat to fellow Filipino, eat and shop for Filipino food and relax. Also can setup up a BPI bank account and setup a registeration for Filipino TV if you want that in the house.
Would be a good day out, and lets your missus see the capital city!
