The greatest sax players I've met or had the opportunity to work with have all been fine clarinet players. I'm telling you- learning how to play clarinet seems to give you an edge when it comes to saxophone.
I have a friend who swears that if you have the time to only practice one instrument, it should be the clarinet. His theory - and I fairly agree - is that the clarinet is so difficult to play consistently well, both in technique and sound, that the saxophone is "easy" comparitively speaking. The transition from calrinet to saxophone is much easier than the other way. I know as I began on saxophone and then began playing clarinet when I was in college - NOT an easy transition, at least for me.
I would also add that you should defintely consider adding flute to your list of instruments to play as well, just from a working musician point of view. Pretty much the last bastion of serious, high paying work is doing show pit work and that means playing all the saxophones, flutes, clarinets, AND oboe, english horn and bassoon if you can stand it... (I'd like to go back in time, find the first woodwind doubler, and SHOOT him...)
I also mostly agree with everything Kiyoshi said about alto vs tenor, and I also agree you will find more work as a tenor player in the long run. Even considering the doubling, find a horn you love to play, an excellent teacher and learn the instrument inside and out as well as you can.
Look at other threads on these boards about the Cannonball horns (I for one, like them very much) and different issues with them. Most importantly, play as many different horns as you can, and take a saxophone teacher (or great playing friend) with you to pick out your horn, to be sure you get a great horn. The most frustrating thing is to have badly performing equipment...
