First I would like to thank those who take the time to help, sincerely.
1 - My city is unhappy due to "its to crowded" what are the potential solutions?
2 - I am still loosing, consitently on Noble

and often what seems to mess me up is a never ending battle defending my tiles from the black flag. Not always but often enough, before I get anything really going these barbies are coming at me 3 or 4 at a time and never ending. It seems like I'm fighting barbies and all the AI civs are advancing their armies. Is there anything one can do to handle this situation?
1. "It's too crowded" indicates unhappiness due to population (one

for every point of population in a city). There are several things you can do in the early game to keep unhappiness from exceeding happiness:
1) acquire luxury resources and hook them up to your trade network: gold, silver and gems are available with mining, fur and ivory with hunting--for the rest, you'll have to wait until calendar and (for whales) optics
2) research monarchy (or build the Pyramids), switch to hereditary rule, and crank out cheap units--you get one

for every unit stationed in the city under HR
3) if you do manage to build the Pyramids, switch to representation for two

in your five largest cities (in 1.61 at least)
4) found a religion and adopt it as your state religion for one

in every city with that faith; research priesthood and build a temple for any religion in a city for one

per temple
Another way to manage unhappiness is through whipping: research bronze working, adopt slavery, and when angry citizens start showing up, pop-rush a unit or improvement to get the city back down below the happiness limit. But remember that you'll get one

for 10 turns every time you do this, so the happiness limit will be one population point lower until the effect wears off.

2. Barbs are definitely a pain, especially when barb axemen start showing up. To deal with them, research animal husbandry, the wheel and bronze working and try to hook up either horses or copper early (preferably with your second city--if you're lucky, one of them will show up in your first city's radius). Then build barracks, followed by a few chariots or axemen. Give the axemen Combat I, followed by Shock when they get up to 5 XP--that'll make them more effective against warriors or axemen. Chariots should be given Flanking I, followed by Sentry--that way, you can use them as fog-busters to make it harder for barbs to show up in the first place (barbs can only materialize on parts of the map that no civ can see at the moment).
