If I read you correctly, this is intended to be "B" bike, or as we used to call them a "stoney bike" to be ridden when conditions are such that you wish to spare the A bike the abuse.
As such, I wouldn't put any more into it beyond what's necessary for it to work decently.
That's something I certainly can't evaluate from a few pictures, but you can easily enough. Simple rule for B bikes. If it's broke, fix it, if not wait until it's broke.
