For low light, I would recommend a lightweight tabletop tripod, such as: http://www.adorama.com/BG709B.html?utm_term=Other&utm_medium=Shopping%20Site&utm_campaign=Other&utm_source=gbase
Perhaps also a monopod that could double as a walking stick. I think a lightweight lens with macro capabilities would be handy. There aren't a lot in that category, so I would suggest the DA 35mm Macro Limited. Definitely a wide rectilinear. I agree with the earlier Sigma 10-20mm suggestion. You also need one of those puffer rocket blowers.
