Will my passport be part of the new system already? Am I in line for inputting into the ID card database?
If by the new system you mean the National Identity Register then since it does not exist you can not be part of it.
In order for you to be in line for inputting into the NIR you would need to be in a situation once the NIR is implemented that required registration on the NIR e.g. you if you are a non-EU citizen or an airport worker etc. If that situation doesn't arise before your passport requires renewal then that would be the next occasion when your data would end up on the NIR. Even when the NIR goes live for UK citizen passports it will not initially apply to renewals but only to new passport applications (although that situation will change in the fullness of time and likely before its time for you to renew).
That was the reasoning behind the Renew For Freedom campaign: give yourself as much time as possible before you are in a situation where registration becomes a necessity.
