I think you are quite right about all the partnerships.
I would say Milan plays quite slow Short passing game, and mostly through the middle of the pitch even though when seedorf plays CML he often drifts wide.
you can play the MC as MC central mid defend and set his mentality very low.
I would play nesta central defender defend and silva as ballplaying defend if you play with a high defensive line but if you set your line lower you could use stopper/cover combo.

look for free players, also you could try to loan some youngsters from the top teams. try to scout some promising regens aswell.
here are some good an cheap players for you:
humberto suazo
f fazio
m pamic
s vrsaljko
v kadlec
j rodriguez
I would go for benitez, you could also take a look at humberto suazo
