Answer 1

If you are using TOM.NET there is IsPublished method in PublishEngine class:

using Tridion.ContentManager.Publishing;
...
    if (PublishEngine.IsPublished(page))
    {
        // Some logic
    }

For more info about the page publishing you can use:

foreach (PublishInfo info in PublishEngine.GetPublishInfo(page))
{
    info.PublicationTarget.Title; // Which publication target
    info.PublishedBy.Title; // Who published it
    info.PublishedAt; // Gets the DateTime at which the item was last published. 
}

If you are using Core Service use IsPublished method of Core Service client:

string pageId = "tcm:10-259165";
if (client.IsPublished(pageId, "tcm:0-0-0", true))
   {
     // Some logic
   }

For more info about the page publishing you can use:

string pageId = "tcm:10-259165";
foreach (var info in client.GetListPublishInfo(pageId))
{
    info.PublicationTarget.Title; // Which publication target
    info.Repository.Title; // Which publication
    info.PublishedAt.ToShortDateString(); // Gets the date/time at which the item was last published.    
}

If you want to do it from a CM side, you could check the last published date of the page, if it is null/empty then it is never published, in other words, it is being published for the first time.

You might want to look at this post to retrieve the last published date of the page:

There are three extension points you have accessible (for writing to content) when publishing.

1. Event System - use the OnPublishPre event and update content. This is after the rendering phase, but before resolving.
2. Custom Resolver - Add or remove items to the resolved content. For example, Component Presentations.
3. Custom Deployer - Get the package of published content and add, update or remove metadata or other content in the Deployer phase.

Unfortunately, with Compound Templating and TOM.NET you cannot modify content at publish time as it was possible in version 5.x and VBScript templating.
