It's best to unplug the battery so the ECU will reset and learn what new parts you just installed. Has happend to other cars that you install a intake without disconnecting the battery, the intakes flow better air but the ECU detects a change and either A. doesnt change anything so you get no gains or B. detects the change and throws a code. Doesnt ALWAYS happen but i had it happen on my other car.
As for the bumper removel. Few bolts on the bottom, few on push pins on top and 2 in the wheel wheel, 2 screws (one in each well behind the liner) and the bumper can be pulled off. Its really not that hard. Just follow the DIY and it should take u a few hours to do everything.
