Pay I've heard is FO pay during training then CA pay after passing your check ride. Haven't heard how long DEC CA training but I would imagine at least as long as FO, maybe (hopefully) longer and more thorough. So you're looking at at least 6 weeks of Indoc, systems, and IPTs. Then 2 weeks of Sims then 2 days of differences ground then 2 days of differences sims. With the temporary halt of FO training you can expect to go straight through with absolute minimal time between modules.

Junior bases are Knoxville and Dayton with Dayton being slightly more junior but I tends to swing back and forth. F we open a new base (Nashville is the most often mentioned rumor), it will likely go most junior. The earliest we an expect to see that though is late fall.
