Ok, this is slightly confusing, but Ill do my best to make it understandable.
Now, I have a RAID 0+1 Raid Controller It can do
RAID 0,
RAID 1 or
RAID 0 + 1
Hard Drive A (20gig)
Hard Drive B (20gig)
Hard Drive C (40gig)

Now, can I take the 2, 20 gigs and RAID 0 those. Now, on same card, use the single 40 to RAID1 the 2, 20's.

Foller?

I don't think so, for the single 40G to become the realtime back up of the RAID0 it would need to run in a RAID Array since the idea of RAID0+1 is 2 on 2. There are more expensive RAID controllers that will allow this & I think its the economical version of RAID5 but then again if you have the money for that expensive card you could just buy the extra HDDs you will need to do 0+1.

no you cant do that you could use your raid 0 for the two 20's and then raid 1 the 40 to the 0 with a software raid but its pretty pointless. since you dont have a 4th drive you cant raid 0+1 with those drives and if you did youd loose 20gb off the 40 anyways. realy the only good solution for you is either raid 0 or raid 1 the two 20g's and then just put the 40 outside the raid array
