No one replied to my second question: how to get standard errors or

Assuming you mean 'predictions based on the estimated fixed effects'
rather than 'estimated fixed effects', for one solution have a look at
Ben Bolker's r-sig-mixed-models FAQ, about 2/3 of the way down:

Googling "lme prediction intervals" turns up quite a bit. Here's a
recent conversation:

Thanks, Kingsford. Exactly what I was looking for, both for code and
explanations of alternatives.
