Just got a Samsung captivate...after navigating Samsungs horrid (in my opinion at least) website, I ended up downloading three files:

Kies_1.5.3.10093_82.exe (126mb)
Kies_Mini_For_Captivate_10082_8_1.exe (35mb)
SGH-i897_Captivate_USB_Drivers_5_02_0_2.zip (3.5mb)

Which of these do i need to install to be able to sync between my PC and phone? Why are there two different "types" of Kies? Do they include the Captivate drivers, or do I need to install those before using Kies? Basically I'd like to be able to backup contacts, SD-card content, download app updates, download firmware updates, etc. Thanks for any help,
