Well, I'm certainly not a photo pro ... but my suggestions would be:
1) Use 400 speed film - good versatility. This suggestion is for general photography. On really bright sunny days, I've worked with 100 and had some success. I also used 800 last year for some night photography and liked the results. But 400 is good for just about any situation.
2) Get a polarizing filter.
