Yes, with the clarification that there is no "mbr information on
sda1". The mbr is the first sector of the disk, *not* a part of any
partition. "grub-install /dev/sda" will overwrite the mbr of /dev/sda
(preserving the partition table), will also modify the embedding area
(the post-mbr gap with msdos partition tables) and will install
modules in /boot/grub/.

Those error messages shouldn't cause any actual problem. There are
some things you could do to avoid them (modify grub-mkconfig to add
"--no-floppy" to all search commands for one), but it's probably not
worth doing.

Your BIOS is presenting grub with virtual floppy drives. Why, I don't
know. Your guess about usb-floppy is a possibility.

grub-install --no-floppy just prevents grub-install from probing
floppy devices, it doesn't affect the resulting grub installation at
all. The error messages are coming from the search commands in your
grub.cfg.
