Root Updating phone for GSM use?

Greetings all, Where can a pretty good tech who is an extreme newbie to Android find some basic instructions for updating a Verizon VS870 (Lucid 2) for GSM operation? The phone's menu says the phone is rooted, I read on other sites about editing the build.prop (I assume that's a file) but I'm lost from there.

...Android for Dummies needed - help! What resources can I research to learn Android basics, rooting, ROM management, etc.?

Well, I've made great progress in 48 hours. I've figured out how to root, push, pull, backup, etc., from an adb session in Windows. So far, I have my original build.prop file backed up, system folders backed up, and apps backed up!!!

So, back to my original need plus more questions:
1. Does anyone out there have notes for enabling GSM for USA operation on a Verizon LG VS870 (Lucid 2 w/4.1.2 OS) or notes for any phone originally tweaked by Verizon for CDMA?

2. Another site has a list of things to tweak for a 3.2.4 OS, but would prefer known good notes for 4.1.2.

3. is there any reason to change any of the lines tweaked with "vzw" (FYI...will not be using it at all on a verizon system):
Line 17: ro.product.name=l1v_vzw_us
Line 30: ro.build.description=l1v_vzw_us-user 4.1.2 JZO54K VS87011A.1370604225 release-keys
Line 31: ro.build.fingerprint=verizon_lge/l1v_vzw_us/l1v:4.1.2/JZO54K/VS87011A.1370604225:user/release-keys
Line 170: ro.build.target_operator=VZW
Line 172: ro.config.ringtone=00_VZW_Airwaves.ogg
Line 194: ro.afwdata.LGfeatureset=VZWBASE

4. This is what I plan to try adding (or editing) to the build:
a. Does anything look out of place?
b. Does it matter where I insert this stuff in the lines of code?
telephony.lteOnGsmDevice = 1
telephony.lteOnCdmaDevice = 0
telephony.rilV7NeedCDMALTEPhone = false
persist.ril.mux.noofchannels = 10
persist.ril.modem.mode = 2
persist.ril.features = 0x102
persist.radio.vzw.cdma.mdn = deleted
persist.radio.ap.phonetype = 1
persist.radio.lte.mm.disable = 1
ro.telephony.default_network = 3
ro.telephony.gsm-routes-us-smsc = 0
ro.telephony.ril.v3 = writeaidonly, signalstrength
ro.cdma.data_retry_config = default_randomization=2000, 0, 0, 120000, 180000, 540000, 960000
ro.gsm.data_retry_config = max_retries=infinite, default_randomization=2000, 0, 0, 80000, 125000, 485000, 905000
ro.cdma.subscribe_on_ruim_ready = false
ro.com.android.dataroaming = false

Thanks in advance,
