> Partitions will be aligned on 2048-sector boundaries
This is not necessary. Menu X, D will allow you to change this to 1.
The 2048 value is just wasteful (an overly safe default). Whether you
care about losing that 2MB is your call...
True I can start at 8, not a big deal.

Looks great. Do you really need partition 1? If it's a BIOS system, the
first partition has no purpose.
ESP is not needed on this system but if I want to boot this disk from another PC with EFI I don't want to re-do the whole partition table. Again 200MB is not a big deal.
Your partitioning is fine. It's not optimal, but it will work as it
should. Just remember to install grub2 on the whole disk (/dev/sda),
not in a partition.
