help with hone stones please

hi all,
i have never used this forum before and i am hoping i can get a reply to a few questions.
my biggest concern is where can i find the honeing stones i need for my straightedge.
i was watching the videos on the beginning forum and noticed that i should probably get three or four different grit for a premium sharpness.

i would also like to find out where i can get the abrasive for the strop that i will need to use to keep my blades in good order.

if you can help me with locating these things i would really thank you for your help as i am new at this.
thanks for your time,
sharkbait
