Advanced "Save as PDF" script that saves 2 PDF presets with 2 different Names

Question

HI Everyone,
I am looking to improve a save as pdf workflow and was hoping to get some direction. Here is the background...
I routinely have to save numerous files as 2 separate PDFs with different settings (a high res printable version and a low res email version). Each file has to be renamed as follows...
Original filename = MikesPDF.ai
High Res PDF Filename = MikesPDF_HR.pdf
Low Res PDF Filename = MikesPDF_LR.pdf
I was able to alter the default "SaveAsPDF" script to save the files to my desired settings and to add the suffix to the name. So with these scripts here is how the workflow operates...
1. Open all files I wish to save as pdfs
2. Select script to save files as high res pdfs
3. Illustrator asks me to choose a destination.
4. Illustrator adds the appropriate suffix and saves each file as a pdf to my desired setting. ("Save As" not "Save a Copy").
5. Now all of the open windows are the new pdfs, not the original ai files.
6. Now I have to close each window. For some reason Illustrator asks me if I want to save each document when I tell it to close window, even though the file was just saved. I tell it to not save and everything seems to be fine.
7. Reopen all the files I just saved as high res pdfs.
8. Repeat the entire process except I run the script specifically designed for the low res pdfs.
What I would like to do is to combine these two processes so that there will be one script that saves both pdfs. From what I understand, the script can't support "Save A Copy" so the workflow would go as follows...
1. Open all files I wish to save as pdfs
2. Select single script to save files as both high res and low res pdfs
3. Illustrator asks me to choose a destination.
4. Illustrator saves each file as a High Res PDF and adds the the "_HR" suffix.
5. Illustrator then re-saves the open windows as a Low Res PDF and replaces the "_HR" suffix with "_LR".
Here is the code for the High Res script, The Low Res script is pretty much the same except for a different preset name and different suffix. Any pointer that anyone could give me would be most appreciated. I am pretty much a noob to this stuff so please keep that in mind.
Thanks!
Mike

Thank you for the reply Bob!
Am I correct in assuming that these few lines of code replace all of the lines that I posted above?
Also, When populating the PDFSaveOptions lines, would the end result look like this? FYI, LowRes preset name = "Proof Low Res PDF - CMYK". HighRes preset name = "Proof High Res PDF"
#target illustrator
#targetengine "main"
for (x=0;x<app.documents.length;x++)
     var workingDoc = app.documents[x];
     var workingDocFile = workingDoc.fullName;
// populate these with your settings
     var lowResOpts = new PDFSaveOptions(Proof Low Res PDF - CMYK);
     var highResOpts = new PDFSaveOptions(Proof High Res PDF);
     var lowResFile = new File(workingDocFile.toString().replace(".ai","_LR.pdf"));
     workingDoc.saveAs(lowResFile,lowResOpts);
     var highResFile = new File(workingDocFile.toString().replace(".ai","_HR.pdf"));
     workingDoc.saveAs(highResFile,highResOpts);
     workingDoc.close(SaveOptions.DONOTSAVECHANGES);
