what format have you got?
If youve got a PS2 then question 1 can't be done without patching (see here

question 2 is a long and tedious process, however it can be done. go to edit mode->edit team->(select team)->emblem->create from scratch->edit pixals.
Then simply follow the high res grid image on tghe screen.
tip:zioom in to 8x and turn the alignment grid on to the finest setting
If its PC, X-bo, or PSP then I have no idea.
