For doing product shots on a table top a tripod is a necessity. It allows you to see a large image in Liveview on the LCD and carefully pose and frame the scene.
Having learned on a 4x5 Viewcamera (sheet film), I prefer to stand to the left of the camera and look at both the camera and the scene. The remote cord MC-LC2, or the ML-L3 infra red work fine.
And then I shoot in Mirror Up Mode. Click once to get the mirror up, click a second to capture the shot. This minimizes camera vibration. About one-half of my shooting follows this procedure. It takes less fuss and time than attaching and then configuring a Speedlite and the results make it worth it.
I find that looking at my scene from the side of the camera enables me to see in far more detail than through the viewfinder.
