After a dozen or so hours, I feel like I've figured out the majority of the mechanics and have a pretty firm handle on what I'm doing for the most part. The only (major) issue I still have is inventory management. My cup runneth over with items, and I just don't know what to do with them all.

How should I be upgrading my equipment - through loot? Through the shop? With innocents? By upgrading it in the item world?

What do I do with gear I'm not using - sell it? Convert it to points for the item assembly? Save it for bribes in the strategy assembly?

As someone who has hoarding issues in pretty much every game he plays, you can imagine how overwhelming Disgaea is to me in this respect - so any help would be appreciated.
