Your journey into the park via Tioga pass is stunning and gives some great views of half dome from another side.
Ps make sure you take binoculars with you. If you need to buy some they can be got at a reasonable price.
Would again urge the first thing you do is the valley floor tour. This gives an overview which let's you get your bearings and a little history in an easy way.2 hours.
