Ingredients to have on hand

Hey I am a fairly new brewer and just switching to all grain. I was curious what ingredients people keep on hand or what would be good to have on hand.

I mainly plan on doing pales, ipa's and wheat beers.

Right now I have the following.

1lb willamette hops
1lb cascade hops
1lb Columbus hops
1lb simcoe hops

50lbs 2 row pale
3lbs carapils
3lbs crystal 40
3lbs crystal 70-80
3lbs of dark mix (half roasted barley half dark malt) - need this to make a porter for my brother.

Any help on what else I should have on hand to build out my on hand ingredients would be great.

Thanks!
