The two symptoms you describe are different issues related to the same thing under the hood: Chunks. These are the base units the game stores/sends/loads/coordinates between different users.
The first is a chunk-loading issue. They are loading slowly, more than likely because your players are using the farthest view range and playing concurrently in separate parts of the map, which forces more sectors to be forced to different machines at the same time. If you are running a MP server wrapper, there are pluggins you can use to augment that, but it's a code/bandwidth problem at its root.
The second is a chunk error. There's nothing you can do about it. It's just shitty code. But reloading the server will probably move the glitch in most cases.
Disclaimer: As with any plugin-driven system, I recommend identifying problems first (things you want not provided by default), then solutions. Adding plugins only makes it harder to maintain, especially when Minecraft updates.
WorldEdit is great for larger-scale construction than is normally feasible. CreativeGates is the least offensive teleporter-creation-and-management plugin I've found. Multiworld (especially in combination with CreativeGates) makes managing and switching between different worlds fairly straightforward.
CreativeStick is another good enhanced-building plugin, but I don't know if it's up-to-date off the top of my head.
So far I have only added the Essentials plugin to the system, which my daughter requested.
Funny thing is that when I created this world last night I spawned on a tiny island with nothing on it. All horizons were blank. Took several "swim that away!" attempts before I found land with anything on it.
Borderguard puts an invisible wall around an area of X blocks to prevent players from wandering and enlarging the map (which causes massive slowdowns if it grows too big).
TextWrap gets rid of the stupid line breaks in chat.
WorldEdit is, in fact, indispensable for big projects. CreativeStick has not worked for some time now (unless there's been an update since I stopped playing).
kFeather is brilliant for allowing players to quickly warp within a line of sight.
Most plugins are completely useless except for very specific events/situations.

1. Bother cat until it makes cat noises
2. Record said cat noises
3. Cat noise sound effect is now that of an annoyed and bothered cat.
When flying in creative mode I can see the dungeons underground before the land on top is drawn.
There was a huge invisible rectangular section near the spawn. Looked about 64x64 straight down. It acted as if the terrain was there but invisible.

Too bad I couldn't place cacti in some of the trickier dead ends.
