NTLM hashes are not maxed at 8, or 13 characters.  If they're capped at
all, they're capped at some extreme limit, maybe 256 or some such.

I don't like using spaces in passwords because a lot of tools and
programs (particularly on the commandline) use space as a delimiter, so
there's a potential for problems there.

That said, usually those programs implement quotes properly, so I've not
had that issue in a while; and if you're only using your password to log
into Windows (like most users), than no harm in spaces.
