gr8.. u got one of the best tires available in the market! good choice!
changing the bulbs wont cause any harm to the headlight cover. im using this aftermarket bulb for like 5yrs now without any issues. infact, if u want a take the visibility to a new level, get urself narva bulbs. look into the forums for the name n u ll find a thread after it. check out the pictures in there and then decide. it ll cost u a bit more then 1000rs i guess.
well, i never recommed Chu Chu... its a real pain in the "ssa" in rainy seasons, water gets into it n it screws the central locking, or if some car with heavy sound system being played passes by, the car starts shouting n at top of all, it would void ur electrical warranty of 3yrs. chu chu serves almost no purpose at all. how long does it takes to insert the key n unlock the car? central locking is there so passengers dont have to wait for the doors to be unlocked manually. these chu chu's r all china maal, i wont get em of my car.
steermatic rims are gr8. if u find them, go for them. even at 26k they are worth the price as they are original enkei rims made in thailand, not some chinese crap. but if u dont find em, even chinese ones serve the purpose well.
as for the seatcovers, i prefer using the original seats without any cover until they start showing signs of wear n tear. seatcovers take away the looks n comfort of a seat (as they change the shape). i got first seatcovers for my 2006 city idsi in december 2011 
but if u really want it, i'd say go for black fabric ones with small patches of black vinyle on particular areas like the outer sides of the seat n the back. i think i have a pic, i ll show it to u if i find it. infact u shud go with watever design or color YOU like, seatcovers last hardly a year or so, u can change to new designs very soon. n if u like it, then u shud nt give a damn about wat others have to say about it 
well, those are my views about what i wud've done if i had bought a new city. thats my way of personalizing the car, u shud go with YOUR way of personalizing the car... because, as some say, the way a man keeps his car is just an extension of his own personality
