The main part of Old Town is not that far from the pier - a few blocks at most.
Couple of places you might want to look at; one is The Doll House - cute store, plus there's a guy in there that hand rolls cigars that are awesome. And when you walk out the door, cross the street, go to the right, and there's a store (can't remember the name) that sells micro fiber table cloths and napkins. Take the measurement of your dining room table with you. The hardest part is finding one you don't like! Wonderful products and great prices.
There are also some good restaurants around - there's even a Senior Frogs if you just want funky!
