Need your help on a cactus ID...again!

[cb977]

Can somebody please tell me what kind of cactus this is? It has lots of sharp little spikes and gets a little fuzzy. It also has a bunch of little red oblong buds (?) on it.

This was all in a 4 inch pot and was looking crowded so I decided to put it something "a little bigger". When I unpotted it, a bazillion little pieces fell apart. I put most of them in a oblong pot which is about 10 inches end-to-end.

I saved some for whoever gives me the correct name, if they want them.

While we're on the subject...anybody have a name for the one in the last picture? I got this in a 1 1/2 inch pot about 6 years ago and it's been in an 8 inch pot for a while. You can have some of this one if you want it too
