Glad to help with your questions

Obviously this depends on conditions of the trail and the physical conditions of the hikers. I am 73 years old and in good condition. Starting from Springer Mtn, I take it easy and plan stops at Hawk Mtn shelter, Gooch Mtn shelter, either Woods Hole shelter or Lance Creek camping area, Low Gap shelter, Blue Mtn shelter, Tray Mtn shelter, resupply and 0 day at Dicks Creek Gap and then go onto Bly Gap and points north. This make a probable 7 day trip.

There are a variety of different option using Whitley Gap and Plumorchard shelters or camping elsewhere. Also be aware that when you get to Bly Gap, you will need to backtrack in Georgia or go onto NC.

A good trail guide such as David "AWOL" Miller's "The A.T. Guide" will help you plan your trips. The guides will provide info on water, shelters and cross roads.

There are no restrictions on camping in Georgia. There are numerous springs for water. All of the shelters have camping. There is one exception - From March 1 to June 1 you cannot camp between and including Jarred Gap and Neel Gap unless you have a bear canister to store your food. 

You have a bunch of options for an overnight. Again best to consult a guide book. There are  a number of paved and decent Forest Service roads which intersect the trail. For example, if you wanted to start at Springer Mtn, there is a shelter at 2.8 miles and a road crossing at 4.3 miles. Or go from Springer to Hawk Mtn Shelter and have second car at High Tower Gap.

Please keep fires in established fire rings, The are fire rings at shelters and established camp sites.

A bunch of places with great views. Among them are Springer Mtn, rivers and rapids at Three Forks, Woody Gap and a little north on the trail is Preacher Rock, Blue Mtn shelter, Blood Mtn, Rocky Mtn and Tray Mtn.

 Hope this all helps. Feel free to email me directly if you have additional question.
