It's no problem about 1♥. Opening preempt with 12hcp is ridiculous.
There are plenty of times when preempting with 12hcp is a good move and I am confident many here would open this hand 4
♥ with a different seat/vulnerability combination. 1
♥ is clearly the mainstream choice 1st/red though.

Secondly, you had best bid 2♥ when vulnerable. But with favorable vulnerability, notice that any of your opponents can bid a take-out x after 2♥. I suggest 3♥ like preempt because it's easy for 2♠, 3♦, 3♣ etc to score better than 3♥ or even 4♥ with down without double.
How will your partner know that you intended the 3
♥ rebid as preemptive rather than a game try? I understand bidding 3
♥ for the reasons gszes gives - the hand has a super ODR and it acts as something of a two-way shot - but if you want partner to take this rebid preemptively you best start coughing immediately.
