I'm using this for perl.

1st, install that. What you mentioned will probably work, but I'm unfamiliar with it, so no idea for sure.
2nd, go find Dlog99 on the GEMS site, you'll need that
3rd, put the script referenced earlier into a notepad file named rccsv2gems.pl, put it in a folder containing the datalog files, ideally not on the SD card.
4th, open up the command window. In Windows 7 just type "cmd" in the search bar, older versions you need to go run->"cmd".
5th, in the command window you need to navigate to the folder you created. Type "cd *path*" where *path* is how you get to the folder you created in step 3, something like "C:\Users\copper280z\Desktop\Data", don't include quotes or asterisks
6th, in the command window type "perl rccv2gems.pl *input_filename* *output_filename* --disable-gps-cleanup", where *input_filename* and *output_filename* are the file names you want to use EXACTLY as they appear in the folder, INCLUDING the extensions, don't include the *'s. The output file won't exist yet, but will be created when you execute the script, I suggest using the *.csv extension. I chose to have you disable the gps satellite cleanup since you probably didn't have any while sitting in your garage, it'll make sure you have the whole time you recorded.
7th, fire up dlog99 and go file-> import, follow the prompts and save it as a *.stf file. Make sure to select floating point instead of the default integer on the import window.
8th, open up that *.stf file in GEMS Data Analysis! (Or AEMData)
