Actually, there shouldn't be too much fuss about which lens to get... You just need to know your interest and how often u shoot them, look at the focal length of the lens and multiply by 1.6x to see if appropriate.
If portrait and wildlife are your favorites, you should be looking at typically anything between 85 - 400mm with or without teleconverters.
As for landscapes, personally, I don't like using a DSLR (well at least for the Canon D30 to 10D series) at the moment cos it's very limited for me to get that really wide view.
I tend to agree with ST1100 somewhat that the lens will make little difference to your shots in terms of sharpness at least. From my experience, I can't see any such difference using an L or the consumer lenses. But of cos, as he has mentioned, it feels good to hold an L around and make urself look professional, though that has very little to do with the quality of your shots. Unless u need a wider aperture in your shoot.
