Bankroll questions, semi-new limit player

[PokerFox]

I play mostly NL Tourneys..i just cashed $2600 on a $11 rebuys on Stars the other night.

I want to start grinding limits..I cashed out 1600 and left $1000 in my account.

What is the proper play, here? I am a pretty solid player with a good grasp of most things, but I want to confirm with the big boys..

Do I grind it out at 1/2 until I hit 1200 and then move to 2/4, or is 1000 close enough to start at 2/4 for almost 300BB.

Also, do I 2-table? I've had experience with it before, but I don't know if it's appropriate to buy in $150-200 and 2-table 2/4 with a 1k bankroll.

Advice is appreciated in advance,

Cheers,
