Don't irigate grassland, not "don't irigate at all" You need growth after all!
In the very start, you need shields, not roads. Hence, road should wait!
roads are highly important. road the city's used tiles, as each one gives you 1 gold. (Drastically increases tech rate, or treasury, whichever way you swing).
Apart from this, play to your civ's strengths. My current game is as zulus (expansionist, militaristic). After basic defence, i build scouts, and expand quickly. I go to wars to eliminate rivals in the hope that i build my army, become an early power (military AND the extra captured towns), and hopefully get some great leaders!
You need to pick your civ with a game plan in mind. Religous should build a defending army and concentrate on culture. Aim for cultural dominance.
Industrious. Get plenty of early workers and aim for high production improvements.
Scientific. Go for literacy ASAP and use libraries to expand your borders and increase science.
Commercial. Go for currency ASAP, and use marketplaces instead of temples for happiness. Get all the luxuries you can early.
(Industrious goes well with science/commercial for the faster road building)
Expansionist. Scout, make early contacts, get techs and settlers from barbarian huts. You should get an early tech lead, use this for either military or financial ends.
Militaristic: War war war. Try to get those all important great leaders, you can get early dominance, and foreign palace/wonders too.
There's lots of early basic advice in this forum, just have a look around.
