Unless you plan on doing a lot of night shooting handheld, I think the 800 is redundant. I'd stick with either the Kodak or Fuji 160 (NC for Kodak, 160S for Fuji), and some 400 speed. Just pick one chromogenic B/W film- you'll find yourself confused if you keep switching back and forth, because the Ilford and the Kodak have different characteristics. I can't say what's photogenic in Hong Kong- I've never been there myself. Singapore, well... Chinatown is worth a half an hour or so... Yes, Singapore has a Chinatown, despite being 85%+ ethnic Chinese. It is one of the few remaining areas with historic architecture. There's also a tiny remaining gatehouse from the old fortifications in the top of Fort Canning park. The Botanic Gardens are supposed to be nice- if you like macro work with orchids, you'll have a fun time. There's also an interesting little "dutch village" in the Holland Village subdivision, which is off Holland Road. You'll have to take the city bus to get to it. While you're on your way there, you'll pass the new US Embassy, which looks like a veritable fortress on the hill. It's not very popular with the locals, who think it's ugly, vulgar, and overly macho.
Your best bet to get anything out of Singapore other than terrific cheap food is to make friends with a local who can take you around to show you the insiders' view. Otherwise, in three days you'll be bored to tears.
