Hated to say this until about 5 years ago, but....................
You really should take the time to get fitted for clubs. The days of walking in to a sporting goods store or golf store and having the option of steel or graphite shafts with stiff or regular flex are long gone.
There are literally hundreds of combinations of shafts, lofts, and everything else that will make the club work as much as possible with your swing.
I am confident a good club fitting can easily shave 5 strokes off your score if you say 90-100 is the norm.
And you don't have to spend an arm and a leg for a set.
As for composition.
Driver? Yes.
3 AND 5 wood? No. I'd go with a 15 degree or so lofted 3-wood and get a 19-21 degree hybrid.
Irons? Very few sets come with 3-irons any more. Many don't even have 4-irons. Get what you like.
I play with four wedges- A pitching wedge (44 degree), an attack wedge (50 degree), and a 56 and 60 degree wedge.
