You need (OK, maybe not need, but want) to take off what hasn't made it to the first trellis, being careful to ensure that your scissors are clean and sanitised, and that the growth is not likely to make any decent sized buds if it makes it to the trellis (after leaves are cleared).
Also clean out any large, fully-expanded older leaves that are past their best-before date, but not any that are supporting buds, unless they are blocking other bud sites.
That should keep ya busy for a few hours, in that space.
