Don't bother with any software except QuickLoad, which you don't need either and probably don't want until you get a real handle on what you're doing.
I recommend The ABCs of Reloading and one, good written manual. I have the Lyman 49th but any of the major brands are fine.
For other data sources, here is a thread
I created some time back that lists all OFFICIAL online data sources. You don't need any more data than that for normal loading.
Use a simple excel (or OpenOffice) spreadsheet to keep your records.
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
