About the best thing you can do is to call your favorite cam grinder, answer there questions honestly and realistically, and take what they give you. They're the experts. They want to make you happy, and as long as you are straight up with them, what you get will be just right.
That said, Mummert and Isky are good sources for cams. You probably want about their smallest offerings, which will be bigger than stock but still very street friendly.
A good way to get a general idea about a cam is to look at the duration @ .050" lift.
Something in the 210s is a hair bigger than stock and will have good idling characteristics and a lower power band.
Something in the 220s will have a little rougher idle and have a slight lope, with a power band that starts at about 1500rpm. In this range, it will start to become more hot rod and less truck.
Something in the 230s and bigger will have a rough, lopey idle with a power band that starts at around 2000rpm or higher. With this, you no longer have a truck so forget hauling anything. Depending on your own tolerance, this may or may not be too big. and this is probably where you will get into that domino effect, where you need to change a lot of stuff to make it work right.
Keep in mind, that is a generalization. It is much more complex than that, which is why you should talk to an expert, and take what they suggest.
