Whoa, hold on. Go back to your old Apple ID if possible. Creating a new one will create more problems that it solves.
Local iPhone storage and Cloud storage are two different things. Not everything on your phone is necessarily in iCloud.
To control iCloud storage go to Settings > Apple-ID-your-name > iCloud and scroll down to see a list of APPS USING ICLOUD and make any appropriate changes. Note: not everything on your phone needs to be in iCloud. You only need critical items that you would want to recover in the event of failure.

In terms of "other" storage see this:
"Other" is data on your phone that is not apps, ibooks, photos, music or videos. This means operating system settings and data, Safari cache, Siri cache, downloaded maps, reminders, notes, stocks, weather data, email, texts, imessages, and data for all of the apps on your phone. 1 GB is normal for Other.
When "other" gets too high it is designed to fixed itself. However, sometimes glitches occur and it stays high. Sometimes an iTunes sync will fix it. Also a restore occasionally will fix it.
Let us know how it turns out.
