Answer 1

First of all, please check if this solution applies to your scenario. From your code i'm guessing that your executing it from some kind of webpart/page.

Second thing is that RunWithEvelatedPrivileges executes code under Application Pool identity. If you are executing it from normal SharePoint content site collection, which is running on different app pool (and account - which how it should be) then Central Administration, you still may not have access to Timer Job, which requires Farm Administrator rights.

Answer 2

don't obtain site or web from SPSite/SPWeb constuctor. you should take it from SPFeatureReceiverProperties

public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
    SPWeb web = properties.Feature.Parent as SPWeb;
    NotifyJob oJob = new NotifyJob("TestJob", web.Site.WebApplication);
    SPMinuteSchedule schedule = new SPMinuteSchedule();
    schedule.BeginSecond = 0;
    schedule.EndSecond = 59;
    schedule.Interval = 30;
    oJob.Schedule = schedule;
    oJob.Update();
}

or

SPSite site = properties.Feature.Parent as SPSite;

if your feature scope is Site
