well, the font i used is called "depressionist three", or something like that. and as for the dots:
(1.)create a new document 4x4 pixels, make sure it is transparent
(2.)choose the pencil tool(hold your mouse button down on the brush tool)and choose the 1px brush
(3.) make a 2x2 BLACK box in the upper left hand corner of the document(you may have to zoom in)
(4.)then all you have to do is, just press CTRL+A, and choose edit->define pattern.
(5.)after that, just use it like you would any other pattern, just choose the pattern fill tool(normal paintbucket, just change the word "color" to "pattern")
(6.)create a new layer within your project(CTRL+SHIFT+N), then fill it with your new pattern!!!
hopefully that helps you out
also, just a tip: try this:(don't read on, if you have a version under 7.0) choose a normal default brush that came with your ps, and if you look at the top right, it will have a little tab that says "brush" or something like that, try playing around with those settings, and you can get REALLY cool effects, from default brushes! you can do this trick to any brush you have downloaded also, you can stuff like angle jitter, and stuff like that.
