I use a Slime air compressor I bought from Autozone, it is pretty quick at getting the pressure up compared to some compressors and it is still compact. Here's a link:

I'm using an Accutire racing tire gauge which I'm pretty happy with overall. Its only downside is that the bleed is a little slow.
