The standard Debian way is to put the desired hostname in /etc/hostname.
If I'm reading hostnamectl(1) correctly, the command you wanted should
have a hyphen in it: hostnamectl set-hostname NEWNAME
However, I've never used this command and I'm not sure what it actually
does, or how it interacts with the traditional Debian configuration.

That depends on what you mean by "domainname". There is a "domainname"
command in the nis package, which sets the NIS domain name. But I
somehow suspect this isn't what you mean. I also suspect you aren't
talking about Kerberos. Or Samba.
Do you mean a DNS domain name of some kind? That's my guess. But even
then, the concept is ambiguous. What are you actually trying to do?
In order for *other* computers to know your system by a fully qualified
domain name, you would need to alter DNS. Either the real live global DNS
that everyone uses, if systems are doing DNS lookups on the public
Internet, or else a local area network DNS server that you maintain
interally. Or else modify the /etc/hosts files on the other computers.
Or perhaps what you mean is something like, "When I type telnet iota,
I want it to act like I had typed telnet iota.gene.local." In this case,
you're probably aiming for a customized /etc/resolv.conf file. Which
in turn means you need to read up on how to avoid having your changes
to /etc/resolv.conf wiped out by roaming bands of daemons. I've covered
this topic so many times that I'm quite tired of it, so just go to
<https://wiki.debian.org/resolv.conf> and read.
Or maybe you mean something else? Please be specific.
