Help: Save as jpeg

Question

Maybe someone can help me on this Photoshop script, or action. I am working on a psd file  with few layers in Photoshop CS4.  I would like to save it to the jpeg  format.
Below is my workflow.
1) Drag and drop 01.psd into Photoshop from A folder.
2) Save 01.psd to 01.jpeg into the A folder.
3) Image options with quality, "5" Medium.
4) Format Options with Baseline ("Standard")
5) Image mode is in RGB color.
6) Use lower case extension.
7) Other options should be in default setting.
The script or action should be able to:
1) Save as jpeg format with similar name as the psd file without adding words or marks such as "copy" or "-".
2)  Save as jpeg format with similar name as the psd file, and able to  overwrite the jpeg file whenever the psd file has been updated and saved  multiple times.
3) Save the jpeg file into the same folder as the source file without creating any subfolder.
4) Not close the psd file, but still keeping it opens in the Photoshop without any changes.
I've tried the script from http://www.russellbrown.com, and Image Processor from Photoshop CS4, but those are not exactly what I want.
Please help, thanks.

Would this help?
Converting non-RGB-files to RGB would need an additional step, but would not be hard to include.
// saves jpg into same folder;
// be advised: this  overwrites existing jpgs of the same name without prompting.

if (app.documents.length > 0) {
var thedoc = app.activeDocument;
// getting the name and location;
var docName = thedoc.name;
if (docName.indexOf(".") != -1) {var basename = docName.match(/(.*)\.[^\.]+$/)[1]}
else {var basename = docName};
// getting the location, if unsaved save to desktop;
try {var docPath = thedoc.path}
catch (e) {var docPath = "~/Desktop"};
// jpg options;
var jpegOptions = new JPEGSaveOptions();
jpegOptions.quality = 5;
jpegOptions.embedColorProfile = true;
jpegOptions.matte = MatteType.NONE;
//save jpg as a copy:
thedoc.saveAs((new File(docPath+'/'+basename+'.jpg')),jpegOptions,true);
