I strongly suggest you read up on some video poker strategies. Especially important is learning to play "close to perfect," and understanding the variance of the different games. Variance can be a big issue. Also setting your bankroll properly in relation to the amount you are betting per spin. (Or at least understanding if you are short-bankrolled.)
Broad concepts, most of the "best" video poker in major casino markets are at a high denomination.
It depends on how you frame the question. If you play 7/5 100 play JoB (the only version I've ever seen in a TR property) it will naturally have a lower variance than the single line version with the same coin in. That said, I'd rather play a single line game with a better return for the same coin in (ie $5 8/5 JoB > 5¢ 100 line 7/5 JoB) even with the higher variance - ignoring taxes. But the trading of variance for EV is not really a question of mathematics for the vast majority of players.
Edit: I personally wouldn't play $5 8/5 JoB.
