Rogue professions.

I'm leveling a rogue on a new server (so no gold) and I don't know what professions to take.I can't decide between mining/engineering (for gs and PvP) and herbalism/alchemy (for gold and rogue reagents). Which professions would be best for leveling and which for when I hit 60?I plan to make a few ALTs as well if that effects my profession choices.
