Get a firm but not hard saddle, and if you're really serious and think you can follow through, you can get a Brooks leather saddle. They say 500 miles to break in but I've heard it takes 3000. YMMV.
Anyway in general, a long saddle with long rails will serve you well. The long rails give you more positions for saddle adjustment and the long saddle gives you more positions while on the bike. This relieves pressure and also allows you to involve different muscles. Further forward means more hamstrings, further back means more quads.
Nose up the seat will put more pressure on your butt, nose down more pressure on your hands.
Everything depends on your style of riding though. I don't use one of those cutout saddles but you might benefit from one. Specialized has a guaranteed fit program if you buy one of their saddles. Local bike clubs may have a saddle exchange program where you can try different saddles.
Get a pair of padded shorts. I don't like gel, some do. I prefer a "natural" chamois style pad.
Lastly, you can't judge a saddle until you're at least 20 miles into a ride. What's good for 10 miles might not be good for 20., unless you plan on doing more than 10 of course. Bring along the appropriate allen wrench so you can make adjustments along the way.
And lastly lastly, you can point the saddle slightly one way or the other depending on which way you, uh, hang.
