As a big fan of 4e who played a LOT for two and a half years (2010 - 2012), my recommendations for the "on ramp" is pretty simple: Buy the Essentials books. Specifically:
Don't bother with the other five Essentials products (Starter Set, dice, three Dungeon Tile sets). Don't bother with the older books (PHB 1-3, Monster Manual 1-3, DMG 1-3, splat books). Don't bother with the later books (Feywild, Shadow, Elemental). This is all the on-ramp you need.
Don't get me wrong; I love the original classes and races, and I love some of the later options from books like Heroes of the Feywild and such. But they're not the "definitive" books in my opinion. If you try these 4-5 definitive books and love the game and want more options, then absolutely pick up the other stuff, get a DDI subscription, etc. I just wouldn't recommend anyone start there.
- Heroes of the Forgotten Kingdoms
- Heroes of the Fallen Lands
- Rules Compendium
- Monster Vault
- I suppose the Dungeon Master's Kit, though this one is the least necessary
