[Q] Email and Contacts Issues topic

So, I'm running the Gmail app and it works fine for my Gmail accounts. Additionally I was able to get one of my Gmail accounts to sync contacts with my phone (by adding it as an account), but then the phone keeps showing me the email even though I don't want to see it. Then I added my Yahoo account to the native Email app and the darn phone added all of those contacts as well. I disabled Contacts Sync, but the "Yahoo" contacts are all still there.. The Yahoo account contacts are a mess and I really don't want to sort them out or delete them. To be honest, here is what I want this phone to do (which is what my last Android did easily):

1) Sync my contacts from a specific Google account. Just my contacts, not my email and not my calendar.
2) Sync my email from a specific Yahoo account. Just my email, not my contacts and not my calendar.

I know there is an option that should allow me to achieve #2, but that option ain't working. Its seems to me that there are no options to support #1. I think that the only way to achieve #1 is to configure my Yahoo through another email app.

Please share any thoughts on how I can configure #1 and #2 successfully.
