Don't feel you need to upgrade anything to make it "clydable". Buy a bike in your price range from a good shop and ride it regularly without changing anything for six months. In that time, any components that aren't up to the task will break and you can replace them under warranty easily.
Anything else is just buying upgrades to show off.
Many of us know from first hand experience that certain wheelsets just arent gonna hold up however if someone is brand new to cycling i agree with your advice because there is no point to make that investment if they arent sure they are going to stick with it.
