Central Administration and the Timer Service are run by the Farm Administrator account. You do not need to change these, but you can certainly change what service account runs them (it then becomes your Farm Admin account):

stsadm –o updatefarmcredentials –userlogin DOMAIN\username –password passWord

I generally run Search under the same service account as what your "SPServicesSvc" is fulfilling. Not much need to separate it out.

The following services must run as the Farm Administrator:

• Central Administration

• Security Token Service Application Pool
