Need help with changing movement speed with template
 

I'm trying to code a template that applies a pair of changes to base creatures it is applied to. I've done everything else I need in this template, EXCEPT these two features:

Increase Speed
The template is supposed to give a bonus to the movement speed of whatever base creature it is applied to.

What is *supposed* to happen is that when you apply the template, whatever the base speed is, it increases by 15 + (5 x DEX MOD)

Remove Special Attacks or Special Abilities
When applied to a base creature, they are supposed to lose any racial or class based special attacks or special abilities.

The closest I can find to "remove special attacks or special abilities" is from the Ravenous Creature from Tome of Horrors. But there's a whole bunch of scripting in that one that I don't understand...so I don't know if I take all of it, or just part of it.
