Smile Stratosphere 2 Help

Good evening ladies and gentlepeoples! I guess I'm the new kid in town and I'm in need of a little assistance.

As the title of my post states, I have a Verizon Samsung Galaxy Stratosphere 2 (SCH-I415) which has been rooted and I think my Kernel is a skootch outdated & I'm not sure how to update without messing anything up.

Just to make things easier, here is my setup:
Model Number:
SCH-I415

Android Version:
4.1.2

Baseband Version
I415VRBMA3

Kernel Version
3.031-947060
se.infra@SEP-100 #1
SMP PREEMPT Fri Feb 8 01:35:31
KST 2013

Build Number
JZO54K.I415VRBMA3

Hardware Version
I415.04

Sorry for such a long post, but any help would be greatly appreciated and thank you for your time.
