Advantage? To me 'advantage' sounds like very unfair gift. Facts however are, that Ferarri was actually very slow with Alesi and Gerhard behind the wheel. Lauda call them idiots once, if I recall. Point is, with Schumacher, Byrne, Brawn and others they improve it as the F1 competition demands and expects. There was no "advantage" handed to them, but they did simply better job than Williams, McLaren and others building the team and the car, and reap the results as they should at the end. Good car, good driver, and you have it. No advantage in that.
I think you need to go and watch 1995 again, they weren't slow they just had horrible reliability (IIRC 16 DNF's in one year). They were actually contenders for multiple race wins, Suzuka, Spa, Monza and took close seconds in Argentina, San marino, Nurburgring, Silverstone as well as an actual win in Canada. With better reliability they could have been serious contenders.
Your second point is confusing two different arguments, if you build a better car than everyone else then your driver has an advantage clearly. You may fully deserve that advantage as a team but you can't claim not to have one.
