Wands with no spells

I know that in the past everyone has discussed wandless magic, but 
as I was playing with my new wands I got in the mail (yes, I have 
more than one, but then, I have 4 kids and we all want to duel), I 
was thinking about the times I have read about characters using 
their wands with no spells.  I don't have the books out at the 
moment, but I think all of you know which parts in which books I am 
thinking of.  Remember when Mrs. Weasley flicks her wand at the 
dishes in the sink and they start washing themselves?  What about 
Snape pointing his wand at the serpent and it disappearing?  What I 
am wondering is:  does a wizard need to "think" of the spell?  We 
all know they can cast a spell with the wand, but I'm thinking they 
would at least need to think of the spell they want to use. Does 
that mean that the wand and it's owner are connected in some way?  
Telepathy, or something of the like?
