Please see this article from LightroomKillerTips

My knowledge of Portfolio is very limited so I may not have the answers!

But from what I have learned-

Anytime to re-edit your 'site' use the https://portfolio.adobe.com/ address.

Then you can open the Settings from the menu on the left where you have-

Analytics, Site Options, Search Optimization, Search Options, etc.

Re: "Downloads" - In Site Options you can disable the [Right-click] menu options, But that will not stop screen-clipping, so watermarks are your decision.

Re: "Likes" - Not that I know of. I am only aware of the [Contact] link.

Re: "deleted image" - I am still learning the inner workings of the editor!!

1) I am afraid that by turning on Sync with Lightroom all off my 60,000 images in my current Lightroom catalgue will be synced in a cloud somewhere. What exactly happens when I turn on "Sync with Lightroom" Does eveything I have start uploading to a cloud somewhere?

NO. Only photos that you have added to a Collection that is marked to Sync. An these Collection photos are not uploaded to the Cloud as full-size files, but intead they are proxy (smart Previews) of reduced pixel size.

2) I do not see a sync symbol to the left of my collections. Will this appear when I turn on "Sync with Lightroom"

YES. And only Standard Collections are capable of syncing (Not- Smart Collections. Not- Collection Sets)

3) If I turn on Sync with Lightroom and I click on the sync button that should be to the left of a collection folder how does it get into Adobe Portfolio from there? Will it show up in portfolio as an album I can add to Portfolio?

When you run Portfolio you have the options to add from Lightroom Albums. Procedure goes something like this:

https://portfolio.adobe.com/

1) Add a Page

2) Select a Lightroom Album

3) Choose (Import Selected)

4) The New Page appears with the selected Album.
