All you really "need" is a handfull of LED's, resistors, switches and some wire. A breadboard is optional, but good to have. Then figure out where your interests lie and buy motors/servo's (if you are leaning to robotics) or moisture/temp sensors (if you are more into gardening). If you are new to electronics, a good multi-meter and soldering pencil may be a better investment than a spendy (overpriced) starter kit. Last but probably most important: a GOOD PSU. Adafruit has lots of guides/Howto's/ideas if you need inspiration...

You are in a maze of twisty little passages, all alike.
