If you plan to switch to synthetic, you will need to do about $4,500 worth of upgrades to the engine to prepare it for the swap. Otherwise, your enging will likely fail within 27 miles of useage with the first batch of synthetic.
All you need to do is drain the old oil and fill with fresh synthetic and a new filter. Simple as that.

Use the Royal purple, or look for some German castrol 0W30 oil- it is the best oil for a ls1. A few autozones carry the oil, if you can't find it you can get it from WS6 store.
