get mine tomorrow - whats the consensus on fundamental setup tweaks and essential sw
 

so im looking to do all the battery saving tweaks, set up nokia messaging, importing phone contacts, some emulators, etc.

what do you guys like as far as:

-misc software settings and tweaks? usability as opposed to power saving

-best media manager?
i need .ogg support for sure, .flac would be better.
any gapless solutions?

-best repositories?

-any other must have or up-and-coming apps?

thanks
