On the topic of the original series run:
You'll need a filler episode guide as you go forward. The filler gets really bad. I mean. You have no idea.

Manga Canon Episodes: 1-26, 28-31, 34-45, 47-49, 51-63, 110, 112-115, 117-118, 120-127, 138-140, 142, 144-145, 150-155, 157-159, 162-167, 191-192, 194-203, 208, 210-212, 215-221, 224-226, 266, 269-273, 275, 277-283, 286, 289, 292-294, 296-297, 300-302, 306-309, 344, 346, 348-350, 352-354, 356, 358-366
Watchable:
Mixed Canon/Filler Episodes: 27, 32, 46, 111, 116, 119, 141, 143, 146, 156, 160-161, 190, 193, 206-207, 209, 222-223, 267-268, 274, 276, 285, 288, 290-291, 295, 310, 342-343, 345
Hundreds of bad non-cannon filler episodes:
Filler Episodes: 33, 50, 64-109, 128-137, 147-149?, 168-189, 204-205, 213-214, 227-265, 287, 298-299, 303-305, 311-341, 347, 351, 355, 357
History side story? Interesting at least:
Anime Canon Episodes: 284
the filler episodes 147-149 are actually good. But introduce a character never to be seen again.
310 342 expansions cap off and end a filler arch, but are generally good viewing, as it starts and ends with him loosing consciousness, and everything in between is just simply bad writing.
