As dave mentioned High Elves get more special and rare choices than the other armies and can take less core choices.
I have a high elf army, approx 4k points depending how i work it.
But whether 2,3 or 4k i generally base it around the same stuff.
I have a 16strong sea guard unit, 12 archers, a lord in a small unit of 5 dragon princes (gets bigger with more points) 15 swordmasters, 15white lion led by korhil, 15 pheonix guard led by caradryan 2 repeater bolt throwers.
Then i give and take with units such as silver helms, lion chariot, more cores depending what i am playing. Also have a few mages, usually two lower level or as the points increase a lord and hero level, or teclis for magic storm.
when i bought the army though i bought all the models i liked and then chucked in some i thought i would need
