Hi scary alien

Stopped by this thread to do some preventative maintenance to my little rooted Eris in case the trackball decides to go wonky on me in the future.
Just have one little (probably dumb question). My scenario would be option 3:
Rooted phone w/non-stock ROM & 1.6.2 Amon_RA Eris custom recovery installed
So I downloaded your
gscript-sa-171.zip, but before I extract it to the root of my sdcard, do I need to delete my original gscript folder that I put there from rooting originally with erisuser1's "Universal Eris Root for Dummies?" before I run the gscript-sa.sh script with Gscript Lite?
And this note you wrote:
"If you have to re-extract the
gscript-sa.zip file (via
Astro) and re-run the
gscript-sa.sh script from
Gscript, its probably a good idea to delete the
gscript-sa script from inside
Gscript (
long-press the
gscript-sa script name and select
Delete)."
Does that apply only if the first try of replacing the recovery image failed and I need to do it a second time?
Thanks in advance and sry for being so longwinded. Just making sure I'm doing everything right

Rooted only a few days ago, but so far everything was easy and GSB is up and running beauuuuutifully!
