As I said before, you don't have to use it. Just make sure that all the important stuff (see here) is covered in your post. This is the code I used for my posts and I thought it might spare you some work. If you want to.
You "just" have to put in actual information in place of every line that starts and ends with '-----------'. I included the coding for the polls, but it might be easier to just use the LJ Poll Creator. In this template I just put generic good/bad poll options, feel free to be as creative as you want.
I used a table for the 'Cast / Characters' section, which isn't very comfortable, even if you just have to put in the names. There's no need to actually use a table for that. If you don't want to, don't. A list is just as good for this.
I recommend to post the entry first to your own LJ, as a private post, to make sure that the coding is okay, especially the polls and the the lj-cuts (which you can't check with the preview option). Keep in mind that a poll that has been posted (even as a private post) is no longer editable (and you can't use the code to re-post either anymore)! So, before you even post in your own LJ, I suggest copy the whole code into a text file. It will save you a lot of frustration, trust me.
ETA: We've had a lot of problems with the polls lately. I think the reason for that might be that polls are posted privately first and then publicly to this community. LJ seems to think it's the same poll and doesn't let anyone fill out the second one. This doesn't seem to happen if you delete the private post in your LJ before you post here.
(And, uh, just to make sure that no one takes this the wrong way, I do NOT think that you are too stupid to do this yourself just fine, I just want to save you all the frustrating stages in between.)
Okay, that's all I can think of right now. If you have any questions / problems / whatever, I am happy to help.
