Since you have requested how to do two tasks and you got assistance - it would be great if you can show your work on how well you could implement. If any improvements can be made, we can assist you.
Also, please make an attempt with the border using instructions below and show the result so guidance can be provided. Just ask if you have any questions.
One approach to create borders:
1) Create Guidelines so that it becomes easy to create border. After looking at the picture, 50 pixels from each side seemed to be a good border width, so we will create guidelines on all four sides.
a) Go to View > Guides > New Guide... then click "Vertical" and set Position to 50 Pixels.
b) Same as above, click "Vertical" and set Position to 1450 Pixels.
c) Same as above, click "Horizontal" and set Position to 50 Pixels.
d) Same as above, click "Horizontal" and set Position to 1000 Pixels.
Now, you should have your guides setup like this:
2) Select Brush tool, Set Brush Colour to White, Size to 20 Pixels, Hardness to 20%. This gives a dissolving look on the edges.
3) We do not need the Guides anymore. Go to View > Guides > Clear Guides to remove them.
4) Select a new layer. We are going to draw our border on that layer. So name this layer "Border".
5) Select Pen tool, click on the four intersections of the guidelines. Your screen should look something like this:
6) Right click, Select "Stroke Path", Set Tool to Brush, ensure Simulate Pressure is turned off and select Ok. Your screen might look like this:
7) Under the Layer Stack window, you will see the Blending Options button as shown in Red circle below:

Select that and select "Bevel & Emboss..."
8) The options I selected and the final result are shown in the below image. You can choose your own options to suit your liking.
Note: I think Pillow Emboss might be closer to the border you requested for. Experiment with the settings until satisfaction.
