Hi Jaime,

See the following link to get started:

The geek group has by far the best buy on caps even if you do have to wait
awhile.  They also have this handy chart about how many caps you need for your
NST:

They have sold like 5000 of them and I guess they got orders for 2000 more... 
sort a take a hint there :-))  I would get 10 or 22 depending on your gap
type.  I would have a hard time recommending any "others" these days.

For the bottles, don't use more than 40 :-))  but use a LOT of them...

Cheers,

        Terry
