You should not strike anything out of your list. There is always a new way to practice things.

As far as what is next, that is up to you really. There are tons fo things you can do, vaults, precision, PK related conditioning (QM's, muscle ups, hand stands) that would go along with your technical training.

Just try whatever you think is more suitable for you. You can always practice a few techniques at the time. Be creative.

Also, make sure you drill your rolls constantly. Make them part of your EVERYDAY training. Everytime you go out and practice try to do a few, both sides.

Good luck.

You can always improve upon your techniques, for example working to get the most power/speed/etc. from your lazy that you can.

What I'd suggest personally is to just get more comfortable moving, running, climbing, jumping, swimming, etc. Getting used to doing things that you may not have done already. I also suggest conditioning a ton if you aren't already(don't overdue it though, an overuse injury is a dumb way to injure yourself) Technique wise you can always improve somehow, no matter how experienced you are. So if you want to work more of the "basic" techniques just kind of go for it, but don't ever stop learning them, don't think "oh I can land a kong, don't have to worry about that anymore" because thats not what parkour is about, you should master your body and your environment, never settle for just landing it, you want to strive for perfection in everything. At least thats how I see it. *shrugs*
