No.  You need 120ns SIMMs

Yes.

80ns FPD (don't worry about that, just tell the chip 
merchant that you want them for a IIci for home use)

>4. Can I mix 150ns and 120ns SIMMS in questions 1 and 2?

No and Yes, respectively.  You can't use the 150's in a II,
but you can use anything that is faster than 150 in an SE.  It
only cares about how long it will take to get the answer.  If
one chip has the answer first, it will not make any difference.
It is expecting an answer there sometime after 150 ns from when
it asks.
