Reasonable questions, but not the big issues you're worried they might be. The alternator will produce enough power when the engine is on to re-juice the battery in normal daytime driving. Pay attention to electrical load by turning off stuff you don't need: if you are running the radio at the stop light, then use the parking break to at least cut the brakelights. Cut the radio when you go to start. If I read my meter right, cutting these things makes more power available to the starter when you restart. Buy a charger: you'll get some or all of your money back in extended battery life.

But most importantly, enjoy the car and don't worry. It was well-engineered and will do what you need.

EDIT: just checked your Pulsar's page. Are you sure that curb weight is correct? 1200lbs is lighter than a VW bug, and half the weight of most civics circa 2000. Regardless, EOC and P&G are pathways to much more in MPG from this car. You've left a lot on the table.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
