I would not suggest that neither.  Usually Dns update around the world in
about 15 min.
And most dns providers don't care for the TTL value you put so it's not bad
to change the ttl but it will most likely not do anything.

Change it when you have your ip and you will be ok.

Subject: [m0n0wall] DNS (Off Topic) Question

This is an off topic question but I figured the experienced users here could
answer it for me.

I'm transitioning from one static IP to another as I switch DSL providers in
a day or two. I've got a host name that users employ to connect to me.

The new static IP is not working yet.  However, in preparation for the
transition and to minimize downtime and failed connections, can I add my new
static IP to my DNS records as a second entry?

Or, am I better just having one entry at a time for my hostname?

Thanks in advance, Ernie
