newbie questions

[skasol]

I am contemplating buying an ipod touch for the gym and I want to know 2 things.
1. where do I get the applications once I jailbreak it.
2. is there a tutorial on how to jailbreak it that is easy to follow.

Thanks all and I am sorry if this has been asked already, I am planning on buying the 16gb on ebay.

thanks in advance
