Truthfully unless you're trying to buy and establish a "comic collection", chances are getting the issues you're after in a Trade Paperback are your best bet.
I know for sure that Amazing 298, 299, 300, 315-317 were reprinted in a TPB called Spiderman Versus Venom back in the early 90's. I also know that Larsens Venom issues, 331-333 and then the 345-347/348 stuff were also reprinted.
I'll bet you that some of the Venom mini-series are also reprinted, (most definitely Lethal Protector is I bet).
Good question is whether or not Spidey's earlier appearances wearing the alien costume have been reprinted or not, (as in his Marvel Team Up and Spectacular Spiderman appearances in the alien costume).
There are books I'm SURE won't appear in any compilation, like the early annuals with him in the costume... BUT... those are like $1 on Ebay at max.
