Answer: I've just watched the scenes back-to-back and the similarities are pretty vague, so I can only assume you're referring to some subtle background noise I didn't notice. Regardless, chances are if they reused the same sound, it was just because it was some sort of licensed music-library sound they thought worked well in both scenes. This actually happens all the time. I've seen movies where, if you listen very closely, you can hear the same sound clip 2, 3, 4 or more times mixed into the background noise. (Ex. "Wes Craven's New Nightmare" reuses the same "pottery breaking" sound about a half-dozen times if you pay attention during the earthquake scenes.)

Answer: Yes... at least in one version of the film. In the theatrical version of the film, Thing merely uses his foot to channel water towards Doctor Doom. However, in the version released on home video, Reid turns his body into a "hose" of sorts to channel the water towards Doom. Evidently, they couldn't quite finish some of the effects (such as Reid turning his body into a "hose") on time for the theatrical version, but finished them for the DVD/Blu-Ray. The DVD/Blu-Ray version also has a few other minor tweaks, such as the music is also slightly different in the final battle. (It is important to note that confusingly, the theatrical version was released in some territories on home video and is also used on some streaming platforms - notably Netflix used the theatrical version).
