Hello Kim,
Welcome to the forum!
1. Yes, the EAs from FSB Pro are slower on Meta Trader tester than those from EA Studio. This is because the ones from EA Studio are simpler, with smaller code, and they have only the MetaTrader indicators. If you have some custom indicators or Longer TIme Frames it will make the Meta Trader slower. Now, this does not mean that there is a problem with the EAs, but more that the MetaTrader tester cannot handle them quickly.
2. No, you do not need to. Whatever indicators you use, they are inside the code of the Expert. You do not need to place them on Meta Trader.
3. When you have the generator running for a longer time, you will have simply more strategies calculated. The more strategies you have, the more will pass the acceptance criteria that you selected to use. So this will bring you more strategies and you will see the best ones on the top. With FSB Pro we have working minutes too. Go to Generator -> Settings:
