I've bought and sold thousands of items on everyone's favorite online auction site!
eBay is a relatively safe place to sell stuff... and you'll see PayPal payment before shipping, so won't have much risk of getting scammed. Do insure the gear going out, just in case something happens in transit. Be honest and complete in your descriptions. Take plenty of photos of each item... both to include in the listing and to confirm the condition in case any questions come up later.
To get the best out of it, do not sell all in one batch. Sell the camera with it's normal accessories (manual, body cap, strap, manual, battery & charger). If you can, get the shutter count for the camera. That's like the "mileage" on a car.
Sell each lens, the flash and tripods individually too, each with it's own accessories.
Small items like extra batteries and filters for the lenses you might just include with whatever they fit, rather than trying to sell those separately. This because shipping them separately may cost more than buyers are willing to pay. By including them with what they fit, you are adding value to the larger item and will be able to ship all together.
The hardest thing on eBay is making yourself set a low starting bid and not impose a minimum bid.... but that's what gets the most bidding activity to drive the prices higher. Setting too high a starting price and putting a minimum bid on it discourages aggressive bidding. OTOH, a low starting bid and no minimum risks an item selling for less than you'd like. But, hey, that's what happens at auctions! Sometimes you eat the bear, sometimes the bear eat you!
Of you can, offer free shipping. That's another thing that can encourage aggressive bidding.
You can do a search on eBay for identical items using the "sold" filter to get an idea what things are selling for. Also do a search that includes unsold items to see what people aren't buying.
If you have boxes for each item, great... include it. People are always impressed to get things in the original box! They actually spend more to get it. Don't worry about warranty cards, because AFAIK the warranties are not transferable (and may be expired anyway, if the gear is more than 1 year old).
If anything happens and a buyer tries to return an item, only issue a refund after it's been received in good order. If you mention a returns policy at all in your listing, specify that buyer is responsible for any cost of return and that the shipment must be insured.
