You have done a good job of your homework.
One thing to consider is your requirement for FLOAT. In general a 5m kite is considered the smallest you want to go and expect anything like float to
happen. Smaller kites will lift you but also drop you faster. Even 5m is a gamble and requires good timing to ride out proper. From about 8m up kites
get pretty slow and while they float well it is tricky getting them turned on time. They larger the kite the sooner you will have to put it down due
to too much wind so it is a balance finding the perfect size for your conditions.
If money is tight , take your time and watch the for sale section on here. At least check on folks opinions here if you find a deal . If getting some
jumps in is the goal I might suggest a second hand 5.6m Twister II ? Or similar?
Yes, you can get a harness and hook in with handles. Doing so will extend your fly time. The trick is to use them to avoid getting tired out but to
unhook when you are trying anything tricky. Soon flopping in and out becomes second nature. Folks riding with handles usually strop in. When you see
folks flying / jumping static it is less common. The BIG advantage with a harness and static is using it to rest up + get 3 times as much flying in !
Yes , sticking with 4 line handles will probably serve you well. Even to get going if you eventually get a ride!
