LOl.... what kind of trees grow in your area? That's what I would use, not because you can make your own chips but because its the smoke most folks there will recognize. Pork and fowl are both short smokes so I would go with a light wood type vice a hard smoke. I like Pecan, but I have trees here on the property.
Don't go over board with the chips, more smokes are ruined from too much smoke than from too little. Start with a light hand and grow with that knowledge. The same with the brines rubs and marinades, if you don't recognize plain jane you don't know how the rest will influence it. Your brides a smart cook.
Try some herbs or veggies in the body cavity. What do you like? Garlic? Onions? Celery? Apples? Oranges? a sprig of Rosemary, or thyme, or parsley, maybe some sage. Heck I tried an apricot chicken and loved it. Use what you know you already like. And Don't get carried away with it. The best foods make a person wonder what that aroma or taste is.
You have got to use something to encapsulate the ribs and birds, usually its either oil or sugar. If you don't the skin will crack and lose juices, not good. Its why people rub. You can't taste it normally.
Remember no matter how bad you know you need to open the lid and check the meats, leave it closed. The first three hours there is really no need to open it. Then add the birds and foil the ribs, clean the chip tray and load it again. Close it up, in two hours remove the foil, sauce the ribs if you are planning that way, check the birds, and close it again. No need for smoke this time. With an electric there is no moping, spritzing, or saucing. Its a long explanation and a personal preference but trust me on it. Leave the smoker closed up as much as possible.
Try the light smoke first, maybe a veggie or fruit and a herb in the cavity. Rub salt, pepper, onion, garlic, and some light brown sugar on the ribs, olive oil on the birds. That's it. You'll be impressed. Don't over smoke it, don't over think it, don't over do it. Its all about relaxing and communing with the smoke Gods.
I don't have an H2O but I gotta ask, you sure you can get all that in there? BTW there is no thermostat on this type smoker, so you'll have to adjust the temp to meet your needs, althought I see its has a high Watt element which is good.
Good luck and remember to enjoy the smoke.
