It's been about 10 yrs since I've tended a garden (used to as a kid then it's been dorms and apartments for me) and recently I've started taking care of my mom's neglected flower beds. On one of the rose bushes, a branch has really gotten out of hand and, as it's growing crookedly into the window screen, I intend to cut it all off. Since it's fairly healthy I thought I should maybe take the chance to make a cutting(s) from it. I have a couple simple questions for the more experienced people here.

1.) Should I weight for the buds to bloom before cutting it?

2.) Where should I cut it at (I know it needs to be about 12in but can it be more since I need to chop off the whole branch anyways)?

3.) Should I make more than one cutting?

4.) Should it be planted into a pot or would directly into the flower beds work?

Here's some pictures of it

Any other tips would be appreciated as well. I've made plant cuttings before but it's just been so long.

Thank you.
