Don't worry, I've played every Champ/FM game since 1994 and I found the 360 version a little 'fiddly' at first.

You get used to it in a couple of days though.
I'll try answer your questions.. *boots up the 360 again*
To select who handles the other teams, go to your main squad screen (LB button, then select your team name on the list, 2nd option down I think), then select Manager - Options, et viola!
If you mean you want to find the training section though, simply go to your main squad screen and hit RB then scroll down to: Sections - Training - Coaches
Some teams start off with players on the transfer list, the game goes on the logic that the previous manager put them there.
To search for players that are listed just for loan, hit LB at any time and scroll down to Player Search. Then hit the X button and select the first option ('Customise General Rules'), then scroll down to Transfer Status. Select it with A and you'll be able to change it to Listed For Loan. Then hit X again when yer done.
I dunno of an FM mag, there was a Championship Manager mag at one time, though I don't know how long it lasted for.
