Let me revise those tips of yours...
Stand-Alone Forums
Don't make them, period. I personally don't know anybody who would base the decision to join or not to join a forum on the forum system it uses, unless it was indirectly (such as if I thought "Well, if this guy bought vBulletin, he's got to be serious", but that would only tell me that said forum would be less likely to be deleted than a free one), but to have a decently active forum, one of its major members needs to be somewhat famous in at least a part of the Pok?mon community, preferrably you. If you're a nobody and all your members are nobodies, nobody is going to hear about it, nobody is going to join, and nobody is going to keep it alive.
Free Hosting
Learn HTML, and find a host where you 100% hand-code your layout. Make sure that if it has advertisements, they're just like Google ads or something, not flashy banners or popups since they annoy your visitors. If your site works out and becomes somewhat popular, you can move to a paid host - after all, why pay for a site that gets no visitors?
Pokemon Sites
There are 563,456,000 pages that mention Pok?mon on the net as of 1st February 2005. Out of them, we can estimate probably around 100,000,000 that are actually Pok?mon sites. Cut down the ones that are just pages of the same site, and we might have like 5,000,000. At least 4,990,000 of them are no longer updated, so we'll take them away. Out of the 10,000 left, maybe 100 of them are decent-sized, and about five of them are the "big ones" that 85 of the others have simply ripped off. The remaining 10 are nice, devoted Pok?mon sites with original content. Make one of them, since the only sites worth looking at out of those 563,456,000 are those 10 and then a "big one" of your preference if you want to catch up with news, and your site is not going to be one of the "big ones".
