Yes, your are right.

SPARC used the FPU IIRC which wasn't too unusual at the time or even now (for integer division).
No, here you are wrong. I just looked it up. SPARC had the "MULScc" instructions which -- contrary to what its name seems to imply -- does not do a whole multiplication but just a single step in (IIRC) a shift-add multiplication. The mnemonic "MULS" stands for "MULtiply-Step". This instruction has been superseded by SMUL and UMUL instructions, of course.
