As for everything else is there anything that MUST be changed or RECOMMENDED to be changed?
Thanks for all help in advance!

A lot of people have been asking similar questions and seem to focus on stock barrels as a weak point of their guns, when in fact guns like the KA M4 have very good stock barrels.
You should use your rifle for a few months before assessing what you want to upgrade in terms of internal parts. It takes a while to tease out
real inadequacies as opposed to imagined ones -- the barrel thing is a good example, since I've noticed some people don't seem to know how to adjust their hopup properly and assume their barrel is at fault.
If you want accuracy and range, buy 0.28g BBs and set your hopup correctly. My favourites right now are the Elite Force 0.28g BBs. You will outrange and outgroup people using Prommy barrels with 0.2g BBs and spend a lot less.
Having said all of the above, the KA M4 does benefit from some tweaking out of the box. The best things to do to a stock King Arms M4 are:
1) Check the seal of the o-ring on the piston and replace the o-ring or stretch it (with fire) to ensure maximum seal. Regrease it. Stock these o-rings come not as tight-sealing as they could. This will improve your compression. The rest of the compression setup (nozzle, etc) is great out of the box.
2) Rewire the gun for Deans or XT60 connectors and wire to the
front. There's a ton of room for larger-capacity 7.4V LiPos in that handguard.
3) Swap the motor for a high torque (neo) motor. The stock ferrite can is weak.
Combined, the last two changes will give you a snappier trigger response and ability to shoot longer than the stock gun would.
