Sorry to tell you this, but apple stopped updating the iOS for the 1st and 2nd generation, and the 3rd gen 8gb iPod touch. I have one too and I'm sad. SORRY!

No, you can use iMessage on a 3rd and 4th gen iPod Touch running iOS 5.
iOS 4.2.1 is the highest iOS firmware you can reach on the iPod Touch 2nd Generation.
The highest possible iOS firware for an iPod Touch 1st Generation is 3.1.3. So you unfortunately cannot get iOS 4.3 on your iPod Touch 1st Gen.
It comes with iOS 4.1
if you mean ipod touch, and its a 4th gen ipod touch or 32gb or 64gb ipod touch 3g, then download the latest itunes, plug it in, and hit update in itunes
No
Multitasking is available only with third-generation iPod touch (32GB and 64GB models from late 2009). However, only apps designed for iOS 4 will allow this feature.
