1. Random players:
If you already created your Historical league, see the screenshot .
If not, then start the game and click create new game. On that screen select Historical. The use Random rookies is right on that page on the left. Can't miss it..
Now if you don't want any changes like teams moving and such in your historical league, go to it's league setup page and click the Options button and uncheck the "Enable automatic evolution of the league" on the left near the top. Or, if you want to keep some and not the others uncheck them individually and don't uncheck the "Enable automatic evolution of the league" option.
2. As for the 2013's real transactions, You don't need to control any teams. You can do it in Commissioner mode. Goto the player's team's roster page and click on that player to bring up his profile page. On that page click the Editor Tab near the top. On that page on the left, you'll see "Team information, Select new team". From that drop down, select his new team and your done. Do the same for any other players involved in the transaction if any.
Good luck
