Friends of ours just started with kiddush - the blessing made on a cup of wine Friday night. Their son was 5 at the time and he really got into it - it was his job to get the cup and the kippah his dad would wear when he made the blessing. They're still making kiddush together every Friday night and everyone enjoys spending some time together. Good luck!
My husband worked out there for 18 months and all I can say is, if you like townhouses, Centreville is for you! It's so new that there are tracts and tracts of new townhomes and then large patches of undeveloped land. Good shopping, though...
Big overwhelming shopping places give me headaches. Besides, if you don't create a registry you don't go "scanner happy" and scan a bunch of things you don't need or have space for. Now I shop for things online one at a time when I need them. I save a lot of money not stocking up on things I'll never need.
