Answer 1

This is the sample code which can be executed on FeatureActivated event
public override void FeatureActivated (SPFeatureReceiverProperties props) {
SPWebApplication webApp = props.Feature.Parent as SPWebApplication;
if (webApp == null)
throw new SPException("Error obtaining reference to Web application.");
// Ensure the job is not already registered.
foreach (SPJobDefinition job in webApp.JobDefinitions)
if (job.Name == JOB_NAME) job.Delete();
// Install job.
SharePointWarmupJob warmupJob = new SharePointWarmupJob(webApplication);
// Schedule the job to run every minute all the time.
SPMinuteSchedule schedule = new SPMinuteSchedule();
schedule.BeginSecond = 0;
schedule.EndSecond = 59;
schedule.Interval = 1;
warmupJob.Schedule = schedule;
// Save changes.
warmupJob.Update();
}

The solution
If you read down the article, there is a zipped solution file (TaskLogger_CustomTimerJob.zip) which you can use and compile yourself.
VS2008 will prompt you to convert project to 2008, just do it and compile.
Building the project
The problem you can't build lies within file BuildSharePointPackage.Targets. MakeCabPath is not valid for your environment. My makecab.exe lies in C:\Windows\system32 path. I tried to change path and rebuild, but it didn't work, it somehow tried to use the old location. So i just copied makecab.exe to C:\Program Files\Microsoft Cabinet SDK\bin and it builds sucessfully.
WSPBuilder
Also, you may want to use WSPBuilder to alleviate the pain on creating SharePoint solutions. It installs visual studio extension which you can use to make wsp file and deploy from visual studio. Download WSPBuilder here, and use Walkthrough of the Visual Studio Add-in
