I can also recommend that a good cart will go a long ways to make life easier. And from seeing a number of other Machinist, get a cart that will be much longer then you box. One reason is the 'open' end will make a handy work space for you tools when there is no bench open/handy. Plus if you are working with large items and will be needing long tooling (36" or longer rulers) then you have the storage for them.
And again if you will be doing a lot of set-ups or such, then plan on having to get wrench sets, socket sets and plenty more. And from personal experience some pnuemantic tools can be big help.
