You could certainly begin talking to other parents now to get a feel for common complaints, things to look for, get a sense of what your neighbors pay their nannies and what duties they perform, and generally acquaint yourself with the hiring/employing side of things, but in terms of sitting down to look for YOUR nanny... I'd say 3 months TOPS.
And yes, visit your neighborhood park, and see if you want the same kind of nanny your neighbors have, or better.
