1. Could someone please assist what's the best practice to update the software version / patch on WLC?
Currently I'm running 8.3.102.0 and would like to update patch 8.3.130.0
2. Would APs restart once the WLC is updated? The APs are in FlexConnect Mode.
3. What's the best practice for standalone WLC?
4. What if we have WLCs in standby mode?
Any suggestions/recommendations please?

For installing installing new base code and also installing the supplementary AP bundle, are two WLC restarts required, or can the base image be installed + the sup bundle then restart?

Correct. Take a backup of the config.

Thanks Leo.
We are planning to implement this change in a week or so.
I'll share details, how it goes.

We are currently on 8.3, is there any stable updated software patch in 8.4.x or 8.5.x we could upgrade to?

Stay with 8.3 and avoid 8.4 and 8.5 (until further notice).

Thanks Leo.
Until Further notice from Cisco? Are there any known issues?
Also, for 8.3, I found following:
The releases 8.3.130.0 (deferred release) and 8.3.132.0 are affected by the caveat: CSCvf87731. This could cause the Cisco WLC to unexpectedly reload, triggered by a timing issue during the processing of multiple join requests from the same AP. This issue could be more prevalent in scenarios of networks with packet drops or reordering.
Therefore, we recommend that you do not upgrade to Release 8.3.132.0, but instead upgrade to a newer release to be made available by October 30, 2017.
Should I go ahead with 8.3.133.0 which would include update for WPA KRACK as well?

Errrr ... Please "read between the lines" when I say: Stay with 8.3.X.X.

Hi Leo,
I'm sorry, but when you say read between lines, were you referring to:
KRACK fix software is now available for download. They are 8.0.152.0, 8.2.164.0, 8.3.132.0 and 8.5.105.0?

Our experience with the patches went like this: We had recently upgraded from 8.0.x to 8.3.130 on our two sets of WLC/Guest Access pairs. This update went only ok, there were changed config items and on initial boot our two secure WLANs were disabled. The WLC GUI helped us through it, we were going again in short order. If anyone is coming from significantly earlier release, plan extra down time for the upgrade.
8.3.130 to 8.3.132 was seemless. Uploaded the main image, then the supplementary bundle (thanks to the guidance here), did a predownload and then reset the controllers. No issues at all.
