Drow/elf question

[Nebuchadnezzar]

In the FRCS, it reads that the drow have all the elven traits as described in the PHB, except the following (and so a list follows).
In this list there is a feature which gives the drow a +2 will save
on all spells and spell-like abilities, yet it does not say it replaces
the elven +2 bonus against all enchantment spells. Is the drow
ability an extra bonus (so that I get both seperate +2 bonuses),
or do I only get the +2 bonus mentioned on the drow list?

 

[BiggusGeekus]

The bonuses stack.

This is why some people think the drow are overpowered at +2 ECL

do they have any favored weapons? (for that matter does any other elves have a different favored weapons list? ... easy grey elves have the same ... hard Aquatic elves have? (prob none))
