Soulcatcher:
Yes.
From the pro tees the 3 wood is not essential.
Masters tend to ditch the hybrid for the extra length of the 3 wood.
Most definitely, Soul!
While I'll usually carry the 3 Wood for the rare times than I'm 240-260 yards out... I've found that I make Eagle 2-5% of the time... and make Birdie 90% of the time. This out of the way, I can make Birdie 90% of the time using an Iron on my approach.
That's why I, from time to time, carry four wedges. It's an awesome feeling to have maximum control from inside [for me] 115 yards. However, it's your choice, as of now I would just get rid of the Hybrid... your call on the fourth.
