It doesn't look like held items are stored in this narc at all.
I know the data is for any of the water encounters...

The 2nd hex after the dex is form for the land mons, but what is it otherwise? In addition to this, what do both of them mean?

Has all of the locations (000 is their Location 1, so 111 will be Location 112.)
They are translated and here, if you want a general location relation to ingame.

There's also the first 8 bytes for each file... what do those signify?
xx xx xx 01 32 01 xx
This is present in the majority of the fishing routes. Undella Town and Location 74 (seasons) are the only ones that are different in the intro hexes.
The locations without fishing do not appear to have these 0x3-0x6 bytes, at least as far as the ones I randomly checked showed.
03 00 01 00 00 00 00 01 -- Cave Wild and Swirling Sand (41)
08 08 01 00 00 00 00 00 -- Outside Wild, Shaking Grass
08 00 01 00 00 00 00 00 -- Outside Wild Grass, Seasonal changes (48)
03 00 00 00 00 00 00 00 -- Inside Dragon Spiral Tower, no sand
08 00 00 00 00 00 00 00 -- Victory Road Exterior, just crag.
06 00 01 03 01 32 01 01 -- Victory Road Interior, fishable cave
with sand swirls and fishing spots.
03 00 01 00 00 00 00 00 -- Cave and Swirling Sand (54)
03 00 01 03 01 32 01 01 -- (71)
00 00 00 03 01 32 01 00 -- (0) Straitron City, only water.
Looks like the 3rd hex is swirling sand/shaking grass toggle, while the 5th and 7th hex are for water spots.
