I'd assign the addresses directly, yes. Unless you're dealing with a
large number of machines (and ones that are changing), then DHCP is just
an extra hoop to jump through. Having said that, there's absolutely
nothing preventing you from using it - providing the DHCP server is
running then everything will work exactly the same in either case.

To solve your hostname resolving problem, you need to add the hosts to
your DNS. This will be the same whether you're using DHCP to assign
them, or have them statically configured.

Yes, get them added statically first, then look into dynamic updates
later (it's not that difficult actually, but it can take a little while
to get your head around it).
