As always do a backup of your device before removing anything
If you don't understand something that is stated please ask, before continuing
1) go into settings and turn off all syncs. Goto settings/apps/ locate the Google apps you don't want running. Clear data and disable each, one at a time. [Leave PlayStore, Play Services, Services Framework, and Accounts Manager intact; I'm not sure about Partner Setup and One Time Init, try those and if not working properly re-enable]
2) assuming you are rooted: you can manually uninstall most of the Google apps. If you know which ones to remove!!! [Leave PlayStore, Play Services, Services Framework, and Accounts Manager intact; I'm not sure about Partner Setup and One Time Init]. I use /system/app-mover [ https://play.google.com/store/apps/details?id=de.j4velin.systemappmover&hl=en ] to switch apps from system to user space, then delete from there.
3) assuming you are rooted: the easiest way of slimming down on the Google apps would be to flash a minimal GApps to your device, that have the core requirements necessary for your apps from PlayStore to function properly. you can add-on any of the other features after that as needed.
Like I stated at the top, make sure you make a backup/nandroid so any issues can be easily corrected.
