Another Turbo Lister Fan here, I list a couple of items every nite, then upload them all on whatever day I want them to end.
MG - Turbolister would be ideal for you coz you can just click your basic description as a *default* setting, then edit the name and the minor details of each listing. Takes seconds.
As for the uploading them, depending on your connection (yours sounds as slow as mine), your auctions will end around 5 seconds apart. I realise what you are saying about last minute bidders, but most will just have a proxy in for the ones they want that end close together and they may drive the end price up for you.
Other than that, you can schedule Turbo Lister to upload them at a scheduled time but it does cost extra. If you are willing to up your start price to cover the additional costs, it should work out perfectly.
