Yes bonemeal is organic but I would suggest fish blood and bone fertiliser.
Stones are ok but dig out medium to big ones. The smaller ones add to drainage which is good for lavendar.
What variety of lavendar are you sowing seed of? For me I would grow them on in pots until they are of reasonable size before planting out in the soil. So, you have plenty of time to prepare your soil
You could plant out some annuals........others here are better at these than me......to flower late spring and early summer and then plant out your lavendar in July?
