It'll never be "normal" but lower Manhattan is open for business and the "frozen zone" continues to shrink. Century 21, a popular store just across Church Street from the WTC site just opened this week, which was a major news story here.
Another big step toward bringing things back to normal will come once West Street reopens. A plan to do just that, which also will facilitate use of the Brooklyn-Battery Tunnel, was announced last week. I don't remember exactly when the reopening is planned, but it's probably only a few months at most.
Resumption of service on the 1/9 subway line is scheduled for November. That will make transit access to lower Manhattan easier, and will be of special benefit to commuters using the Staten Island Ferry, although the stop at the WTC site (Cortlandt Street) won't reopen until there's some sort of reconstruction plan in place for the entire site. Finally, what might be the biggest step of all toward bringing things back to normal, the resumption of PATH train service to New Jersey, is anticipated sometime in the second half of 2003.
