First of all, Congratulations on buying ur new car... i ve got a 2006 city myself, though a manual one... and secondly, welcome to the thread 
So, as far as ur car goes... unless there is something wrong or periodic maintainence is due, u dont need to get anything done. the only one thing that i just cannot emphasis enough is ... the CVT oil!! Get it changes ASAP if the previous owner didnt or even if u dont know if he did or not... and use Honda's original CVT oil ONLY... no other oil works for vario... its a very delicate transmission, you gotta keep it well maintained to keep it going for long... other then that, if there are any sounds from suspension, get them checked. get new air filter , plugs etc and tappets adjustment done if it needs. may be engine oil... you havent stated the mileage of ur car, im assuming its below 150k kms and since ur car is petrol driven, i'd suggest u use havoline formula or Zic A.
Im sorry i cannot help u with a mechanic, i hope some isb/rwp member will help u with that soon... just one thing, dont let the honda dealership guys fool u (they love to do that to make money) unless u or sumone u know trusts them, dont take ur car to them... most of the times they are not experts and people just think they are because of the name behind them...
