Unfortunately, it is going to be very easy to get overwhelmed by the info quite quickly. To address just the Walmart question, I'll tell you that a couple of weeks ago I was out of state for a week without any of my gear, but lots of opportunity for shore bass fishing. I went to Walmart and spent about $90 on a decent enough Mitchell spinning combo, line, plastics kit, jig, hooks, weights, jig heads, spinnerbait, $8 backback, nail clippers and the only other thing I needed was a $10 temp non-resident license. I caught bass all week and the combo should hold up fine for a couple/few seasons in regular rotation.
