Electronic – I need help identifying two passive SMD components from [ GoPro Hero+ ]

This is the bottom side of the GoPro PCB. I marked the components I need identifying. I assume they are either capacitors and/or resistors, but I need confirmation.

These components are SMT components, most likely 0402 size (seeing as there are smaller SMT passives on the board which are probably 0201's).
The device with the mark next to the pulled of SMT's is most likely a sot666 package.
The black one is a resistor.
The tan one is a capacitor.
By the looks of the top layer copper, they are in an RC configuration with both connected to the sot666
There is no way to know the value of a resistor by inspection.
You'll need to measure the resistor with a DMM (in ohms mode) to find its value.
While capacitors do have color codes, in many instances these are manufactuer specific, the best way would be to measure it. It's most likely that the capacitor is lower than 0.1uF in value.
If the intention is to repair the board, then you probably don't need to find new components, just clean the pads off the old components (as they have been ripped off of the board). Scrape the copper off of the traces and find a very very small gauge wire to connect them all back. This will be a difficult repair due to the size of the components.
The brown thing looks like a capacitor. I looked up the Delco Ignition System. Had no idea how that worked.
Here is a photo of an old brown cap I have. The Delco Ignition needs a Cap to function. Not sure what exactly the rest of the board looks like, but if you could provide some more "context" it may be simpler to discover the mystery dome component.
Your U10 is a Microchip 24FC256 - spot the logo in the pin-4 corner?
I suspect that your U9 might be a Linear technology LTC1663.
The pin connections for VCC(pin-4) and GND(pin-2) are almost certainly correct, making C46 its decoupling cap.
