Video voiceover/dub tips & tricks?

Hi guys!

Very recently i got a gig doing cartoon voice overs (overdubs?) and i was wondering if there are any members out there that are experienced in that field that would be kind enough to share some wisdom and advice?

I am kinda getting into it but am looking to speed up my process of recording AND more importantly, to speed up my process of EDITING the recorded audio and syncing it up to the video.

I would love to hear people with experience sharing their workflow and techniques and am very eager to learn new stuff since this is a new experience to me.

Thanks a lot in advance,
