If you are looking for a place to stay before you start your hike, consider the Hiker Hostel. Google it. Not only is it a fine place to stay the owners know the trail. After Springer the trail crosses several forest roads and they can shuttle you to and from several points. Check out their option of "slack-packing through GA". They can drive you within a mile of the start of the AT if you do not want to hike the approach trail.
30 miles into your hike the trail crosses Neel's Gap. The trail goes right through a walled arch that is attached to the Walasi-Y Outdoor Center and outfitter. It is a perfect place to send home gear you do not need or get different gear, clothing, etc., and there is a shelter just beyond it plus it is a small hostel. They have a small food supply, too. The trail has plenty of ups and downs as you would expect. At mile 76 you will cross into North Carolina!
PS I notice you use a steripen. I carry a 1 liter pot on the outside of my pack. So, when I come to a water source , I can quickly fill it, use the pen, drink a liter and carry very little water at one time. Works great.
