careful with the LST, dont want to bend them to much to soon yakno?
I think they both look pretty good for cloning. Cloning isnt that hard if you just stick to instructions. Also one of the most important things that never really get talked about when cloning is the light. You dont need much light to root a clone, a simple t5 shop light works perfect, so just make sure you dont overdue it with the lighting. Keep the soil moist at all times, make sure you take a clipping that comes from the main stem, and make sure its not to big or to small. Also dont leave to much excess foliage on the clipping.
Faqs has alot of good stuff on cloning, I would reccomend reading it, then posting any extra questions that you may have. We would all be glad to help. If you have 400hps I would let them veg a bit longer, because you will have the light necessary to penetrate a bigger plant. That is a big reason on depending when to flower.
Best of luck to ya mate <3
