Yes, guineas are noisy, homely, and pretty dumb to boot. They will get rid of your ticks, and lots of other insects too. You can let them run in your garden, and they will not tear it up, as chickens do. They are very hard to confine, and I have never seen any that were as tame as chix or dux. Chickens and ducks also eat any bugs they can find, but they are much harder on your garden, and you would have to control them for their own protection. People with a bad tick problem usually get used to guinea noise. If you have a neighbor close in, the neighbors may not get used to them.
As always, I recommend the designer recliner - living in and observing your place for a year before you draw up your permaculture plan. Of course, you won't want to do that. So there a few things that you can do that are unlikely to lead to major issues later.
Read permaculture books, especially Gaia's Garden, by Toby Hemenway. Get it from the library if you are wary about spending money on books, but my guess is that this is one you will eventually want to buy. Read John Jeavons' book on gardening, and pay special attention to what he says about soil building.
Map your land. Gaia's Garden will tell you how and what to map, and why you need to know. Have you identified the plants already growing on your land? What about the non-domestic animals who are sharing their space with you? How are they using the land?
For now, confine any livestock purchases to poultry and rabbits. You can make their housing portable. You don't necessarily know yet where the best place for housing them will ultimately be. And one of the wisest comments ever made to me was by a permie land owner who had no chickens, let alone other livestock. He said he wouldn't have anything that wasn't well-integrated into the energy flow of his place, by which he meant, among other things, that outside feed purchases should be non-existent. One you really start thinking in terms of energy flows, the light bulbs will go on, and many questions will resolve themselves.
Do you have deciduous shade trees to the southwest of your house? These could be standard-sized fruit trees. Make sure you don't plant them too close to the house.
Start planting "fedges" along your property lines. These could include nut and timber trees. Just pick a section and start, don't do the whole boundary at once. Get a small section or two well-started.
For now, stay open to the idea of moving your veggie plot. As you learn more about your land, you may realize that another spot would be better. So make any fencing movable, and box in those beds, to make it easier to move the soil that you have been building up.
Do you have a rainwater harvesting system?
Compost everything you can get your hands on, and actively scrounge compost materials from your neighbors. It's a good way to get to know them!
Rethink the lawn idea. For now, maybe just sow a pasture mix and watch how the different plants grow in different spots. You can mow it a couple times in the summer and get lots of green stuff for animal feed and/or compost. The people who sell you the pasture mix should be able to tell you how often and when it's best to mow it. (You probably won't be able to use a lawn mower for mowing the pasture mix.) Consider carefully the reasons why you want a lawn - there are probably other ways to get the same functions that won't be so input-intensive.
Spiders in the house are your friends, and very interesting to watch. You may have venomous spiders, but the vast majority of them are harmless. Learn what's venomous in your area. Kill those, leave the others alone. Remove unoccupied webs.
Hope this helps.
