Let me compliment you on your choice of guitars. Teles are great all round guitars. As far as your question goes regarding fret board materials. I don't disagree with anything that's been said, however, I really doubt that you will hear any major differences in tone. Remember tone it's mostly in the fingers not the fretboard. B)
I've own, or have owned a number of Teles. My personnal favorites are the "52 tele reissue" and the chambered maghony "Telesonic" with DeArmond pickups. I very rarely play these guitars any more since I got my jazz box, however, I just can't part with them. I've also been lucky enough to play various vintage teles including a real 52, 62, Esquires, and various thinlines. These are amazing guitars. Leo got it right the first time! And for the record I like my tele with a maple fret board. It looks cooler! B)
