front suspension

So I need help figuring out how to lift my BB without causing damage to the upper radiator to take off forks and change seals. Any suggestions?

Alright total noob to modding bikes (4runners are a different story!), Does it matter if you upgrade the forks or rear shock first? Eventually want a Penske ($$$$) back there, but in the meantime would it be unwise to upgrade the front with something like heavier racetechs and leave the rear...
