Doing a swap where you install a B-series engine with an automatic transmission is not as simple as it sounds. I remember a few years back a member did one and he had a hell of a time. He said when he was finished, he basically ended up with a complete in-car (the one you have to remove the dash to change) from an Integra to get the Integra transmission to work. I don't recall his screen name or who he was, sorry.
I would probably recommend you stick with a D-series engine. You could probably find a complete low milage D16Z6 from a '92-'95 Civic EX coupe or sedan or a '92-'95 Si hatchback with an automatic transmission and ECU for less than $750 (probably much less as most people won't think of an automatic equiped engine as being worth much). It's a 1.6L SOHC VTEC engine that makes 125hp and has probably one of the biggest aftermarket's available for any import engine (if they make it, they probably make one for the D16Z6). Your only real limitation on power will probably be what the transmission will survive.
I think Baer brakes would be overkill for a street car. I have brembo blank rotors (no slots or holes) and a set of AEM front pad with goodridge lines and the brakes are strong and fade free (for street driving). There are good suspensions a plenty out there for a '92-'95 Civic and even a few different sway bar options. It all depends on how much ride quality your willing to sacrifice and how much your willing to spend.
