Hi everyone, I am new to xda and relatively new to modifying my VZW LG G2. I am looking for some general information on making modifications to APKs as I am trying to change a few things on my phone's interface (rooted but running stock VS98011A 4.2.2 firmware with stock launcher). I am familiar with rooting, TWRP, flashing mods, Xposed modules, apktool, adb, and making basic changes to APKs. I have been able to use 7-Zip to modify images within system APKs to do things like change the app drawer icon and change the status bar icons to all white but for the most part that is the most I know about modifying APKs. I have used apktool to decompile a few APKs successfully (including loading framework files) but I am not really familiar with recompiling them (I always seem to get errors but the APK still builds successfully), signing them, etc.

Here are my general questions:
-Where do odex files play into decompiling and recompiling APKs and do I need any special tools to be able to deodex and decompile an APK, make changes to it then recompile and reodex it?
-Do system APKs need to be signed after being recompiled?
-What is the best tool to sign APKs?
-What are smali and baksmali and do I need them?
-When attempting to recompile a modified copy of LGSystemUI.apk using apktool, I get the messages "W: Could not find sources" and "aapt: warning: string 'sp_remote_info_NORMAL has no default translation in C:\Users\Sean\Desktop\LGSystemUI\res; found: [long list of languages]" but the APK still builds. Is this of concern? Does it have anything to do with the odex files or the framework files?

Sorry for the bombardment of questions. I have read several posts across multiple android forums and can't seem to figure all this out.

rooted VZW LG G2 VS980, stock firmware (4.2.2 VS98011A), stock launcher, running LG G2 Xposed module
