The only benefit to levelling up is to unlock decorations.
From the "Experience" page on the wiki:
Experience and level mean very little in Clash of Clans. A common mistake new players often make is thinking that level has a factor in matchmaking or loot, it does not. Trophies are the sole factor in matchmaking, and Town Hall level is the major determining factor for available loot. The only thing level affects with regard to gameplay is Decorations.
Decorations have a minimum level requirement as described in the table below:
Yes this is possible. What your friend is going to need are at least two Google accounts linked to his phone.
First, from within Clash of Clans, go into settings and connect the current village to a Google+ account. This will allow him to restore his village from any device that he signs into his Google account from.
Then in Android,go to settings -> Apps -> Clash of Clans, and 'Clear Data'. This will wipe the village off the device, but it will still be linked to the Google+ account.
Now open Clash of Clans again and get past the intro tutorial. On your iOS device, open Clash of Clans, go to Settings -> Link a Device -> This is the old device. On the Android phone, open Clash of Clans, go to settings -> Link a Device -> This is the new device. Follow the steps to link the Android phone to your village. Now connect the new village to a second Google+ account (Must be different than the first one!)
Now any time he wants to switch between the two, he just simply needs to Clear Data as explained above. After loading Clash of Clans, he will be able to sign into a Google+ account (there's now an option to do so without doing the tutorial), and restore its respective village.
I just tried this entire procedure and verified it works.
For future reference, it appears that Android phones will soon be getting user profiles. So that like Android tablets, different user profiles store different sets of user data. When this feature comes out, it would be possible to setup each village on a different user profile and just simply switch between the profiles, no clearing user data needed. Though I would always recommend linking each village to a Google+ account for safety.

Directly from the wiki,
“ You cannot cancel the research while it is in progress, but you can immediately complete the upgrade. There are two methods to do so: using Gems, or with the relevant Magic Items (a Book of Fighting for troops, a Book of Spells for spells; a Book of Everything can be used for either).”
