Congrats for the City and the new born baby.
Nice upgrade plan. I'd like you to consider a few more items to the list. I also bought City 2012 White with Navigation and so far I've just ordered the tyres.
1-I'm sure sooner or later you will be looking for a number plate. There is a guy in Islamabad who makes amazing number plates and he ships them to Lahore / Karachi regularly. To see his work, see the photo albums on his page Sticker lovers | Facebook
2-Seems like you are more into cosmetics. Fog lights give a very decent look. In islamabad fog lights of honda city are available in 3000-10,000 price range.
3-If you like to improve lighting while traveling in the dark. Philips X-treme Vision H4 is really what you need. They promise to give 100% more light without freaking out the driver coming from opposite direction.
4-There is a variety of mugen / modulo based body kits available. If u've ordered side skirts then changing the front grill could also be part of the menu.
I myself am currently stuck at installing the security system. Doing that voids the warranty and that's why I'm thinking to do it after a couple of thousand miles (so that i could claim warranty if a manufacturing fault appears during initial running)
