I'd start with the partial grille block if only because it's quick 'n' easy. Instant savings vs. the more complex parts you're considering.
I think this might be what MetroMPG was talking about... Not sure though.

I used aluminum sheet (roof flashing) for portions of the underbody that are closer to the exhaust system. The main consideration around the wheel/suspension area is to allow space for the full range of movement of the suspension and the lock to lock pivoting of the front wheels.
