Ann, Congratulations on your move to Atlanta--I have several clients who have moved here from the Pacific Northwest and love it!
Though the intown Altanta market (where I sell) and close in suburbs do see multiple offers that sometimes exceed list price (more often seen intown), it's definitely not at the level that people are seeing in Seattle and California.
That being said, the best listings will go quickly and you want to have a sharp agent on your side that knows the market and the tricks of the trade (and also how to protect you financially and legally) should a bidding war occur!
Hopefully you can get a chance to come to Atlanta at least once and meet with a qualified realtor. I'm a certified corporate relocation specialist, and part of my skill set is helping relocating buyers get a "feel" for different neighborhoods and what they have to offer, so that my clients can narrow down the areas in which they'll want to live.
But there are lots of great agents in Atlanta--I recommend you do a little research, make some phone calls and find someone who you feel is well-qualified, will look out for your best interests and that you can communicate with.
Best of luck!.
