I know it has been a few days, but...
There is a good how-to on window adjustment and fixing leaks in the how-to section:

.
There are also how-to posts on adjusting the cheaters and the hood seals
As for sealing the snorkel, mine had been done at some point with a glue gun but the job had ultimately failed. I bought some self-adhesive neoprene (closed cell) foam (as suggested by Airportable). I bought it from
ebay
by the meter. The bolts holding the snorkel in place should have some spacers to prevent the crushing of the neoprene. These are quite important.
