First off all i would recommand you to read some guids:

It depends on your Hardware. If you use your CPU for plotting i would say 1-2 day(s). If you use your GPU your plots are ready in 0.25-1 days.
With 2TB you would make 200Burst a day (~9-10Burst per hour) if you choose the right pool. Mining is online, but needs very low bandwidth.
With this plotsize you will make ~2.10USD a month if you mine 24/7. If you have to pay for the electricity and use your desktop-pc your electricity bill will be higher than your earnings. If your pc is running 24/7 even if you don´t mine you are fine. If your HDD was 50USD, your will make profit after 2 years if the price of BURST does not change.

With 2 TB you should choose a pool from here (http://observer.ddns.net:1111/) with a high Target-deadline. (pool.burstmining.club / pool.burstcoin.de / burstpool.ddns.net:8080 / pool.burstcoin.eu)
