How to help bitcoin consolidate as a currency?

It comes to my mind a few things but the most important ones are:
- Have some cash in one exchange (fiat). Each time we need to buy something online, try to find a place we can buy it in bitcoins. Then we just buy the right amount of bitcoins and we purchase the item. For this I would suggest to have the cash in exchanges like btc-e where the price per bitcoin is lower than mtgox/btcchina.
- Tell everyone (friends/family) to use it. Help them to create wallets and teach them how to use them.

Any more ideas? How can we help bitcion adoption?
