Tycoons? (And a small second question)

I love tycoons and I want to make once myself, I know how to do the basic touch buttons, But I want it to: A) Accept it only if a certain player touches it B) Accept it only if the certain player has the correct amount a [INSERT VARIABLE HERE] C) Make the blocks appear if the button accepts the 2 above criteria (Preferably animated instead of just appear (a bit like in 'THE CONQUERORS'))

Might some help me out here...I'm quite literally horrific at Lua.

How do you counteract the inertia roblox added in a recent update (making blocks harder to move).
