Jumping in with both feet - top ten suggestions?

[Analyst]

Playing around on Stars last night, I saw that they have FPP satellites for the big Sunday $215 NL tournament. What the heck - I've never played NL but have a chunk o'FPPs sitting around, so why not? Anyway, for 500FPPs I entered a 27 player SNG, and despite being up against clearly better players (especially when we got HU), wound up winning for a seat in tomorrow's tournament.

I've played a handful of limit tournaments and haven't done badly (even won one), but NL is foreign territory. Today I'm going to get HOH and do the Cliff Notes read-through, but any other quick hints for a NL rookie on keeping my head above water tomorrow?
