Those indicate the LAX Class B airspace. So yes, you need to avoid these bits of airspace except for the portion that the mini-route crosses.

Understood.

Let's look at this in two parts: The first and most important issue is safety. When overflying water, you should plan your cruise altitude to give you as chance to gliding to land in case of an engine failure as you can. So the cruise altitude would vary based on the glide performance of the aircraft. (My good friend and first flight instructor was lost over V-27 in the area we're talking about, so this subject hits close to home for me.)
The second issue is airspace. If you're on an IFR flight plan, crossing Class B is not an issue. Conversely, if you're VFR, then yes, you'd need to cross above 10,000'. However, V-27 + V-25 is outside of LAX Class B, so any VFR cruise altitude would be acceptable, but not necessarily safe.
We should probably break this out into another thread is there is more to discuss.
Hope this helps!
