"What seems to be more profitable: cash games or SNGs?"

Cash games, especially longterm.

"Which has less variance?"

SNGs have less variance than LHE, and O8 has less variance than SNGs. E.g. 4 tabling the $55s you really want at least a 40 buyin BR. To get a similiar $/hr, you could play 3/6 O8 which only requires maybe $1200. With $2.2k, you could play 6/10 O8 anyway and make much more.

"I'm thinking of learning about O/8 and then starting off with around a $600 BR. If I started playing cash games with this size BR, is 2/4 a good level to be playing? If I started playing SNGs, what size buyin would anyone suggest?"

2/4 you could get away with $600, although I'd want more. I've been playing .5/1 for the last 10 days getting used to the game. However, I did have 1k of party skin bonuses to clear [img]/images/graemlins/wink.gif[/img] I'm playing 2/4 now. Start at .5/1 until you are comfortable with the game. Then move to 2/4.

"If I started playing SNGs, what size buyin would anyone suggest? "

I assume you mean O8 sngs. Same as NLHE sngs.

You can get away with a smaller BR if you are willing to drop down in limits when necessary.
