The swim has to be unaided - if you wear a suit you need to wear lead to cancel out its buoyancy.
Goggles are fine - any sort of floatation (ie suit) or method to increase propulsion (fins) are banned.
If its a pool then just a swim suit and goggles. If its the sea, a wetsuit,lead and goggles.
Any stroke is allowed - provided you don't actually touch the bottom or side you can get from A-B using whatever combination you want although i suspect you'd struggle to make the time if you just did breast or back stroke.
Snorkel also no buoyancy aid as above but its mask, fins and snorkel.
The drag effect make shave some seconds off if at competition pace but i cant see a suit vs no suit making any real difference to a normal swimmer.
The 800m snorkel i found very easy after months of 3 dives a day, 7 days a week. The 400m swim damn near killed me and i scraped a 3 score by 2 seconds.
