Talent points.

Ok I am a lv 24 blood elve warlock wondering EXACTLY what to spend my talent points on over the summer (I calculated it and it will take me 2 months to get to lv 70 when summer starts). I did a little studying and I thought 11 points on destruction to get shadow burn and 41 on demonology to get fel gaurd... but i need to know EXACTLY what to spend it on( for exaple somone might say "with your first few points spend it on felgaurd." [if felgaurd was availible for the first few points]). So please help me out with this delema.
