Look up URI - University of Rhode Island County Cooperative Extension Service for information on the varieties that grow well in your new climate. I used to garden in the same zone as you live now, but when I moved I trusted out local county cooperative extension service to give me good local information.
All planting calendars are a guideline - nothing is carved in stone. Some people rely on the Old Farmers' Almanac calendar. For my money, I wouldn't put the eggplant in the garden in Providence before mid-May, but that's me.
Yes, always keep a journal - that will also help later for crop rotation, etc. And take photos, because we like to see pictures!
