Judicial process is a very methodical thing. Lot's of paper needs to be filled with words and filed properly. Judge needs to review and condense all that and put it together into a judgement that is well reasoned (well, there are layers that assist with that).

As for what happens between conviction and sentencing, the typical law answer is: it depends..

He certainly has been in jail for some time already, as he could not help himself from doing stupid things, like contacting witnesses. Maybe it continues, maybe not. Maybe he'll be free for some time after sentencing too. They set a date when he has to show up at the prison.

Until then, it's mostly up to the judge. If he is deemed a flight risk, or continues to run his mouth, he very well may spend the time up to his prison sentence in jail. Though, as he cannot mess with his trial any more and he is not generally a danger to community, he could walk around some more. It depends..

Considering his bail was revoked before and the notoriety of the case, I have a feeling they are going to make him wait behind bars.
