Rails - Mar 2009 - 2 Issues - On load component hiding ; Separate find methods

I have been working on developing a blog site using rails. This is my
first rails application, hence I am fairly new to rails development.
Over the past week, I have encountered a few issues and hence I am
putting them all in one post here. Please feel free to comment on any
of the below mentioned issues:

1) On my blog post I have my blog entries and their respective
comments. The visibility of the comments is toggled using a link. When
my blog page loads, the comments are being displayed by default.
However I want to hide the comments on page load and show them only
when the "Comments" link is clicked. I am using rjs to toggle the
visibility. Is there a way to hide the comments on page load? The code
that I have is shown below:

//Comments link: (blog.html.erb)
<%= link_to_remote pluralize(blogentry.comments.size,
''Comment''), :url
=> { :action => ''show_comments'', :entry =>
blogentry}%>

//RJS Templates : (show_comments.js.rjs)
entry = params[:entry]
page.visual_effect :toggle_blind, "Comment_box_#{entry}" , :duration
=> 0.5, :fps => 50

2) I have also tried to categorize and archive the blog entries. For
that I am calling custom find methods. They are working fine and
everything is being done in the same method in the controller. Also I
have a single view file. However I would like to know if there is a
better way of doing this. Should I perform the find in separate
methods and have separate view files for each find (like separate view
for archives and categories)? Although I don''t think that would be a
DRY implementation.  The code is shown below:

//page controller
def blog
    @category = Category.find_by_name(params[:category_name])
    if (params[:category_name])
      @blogentries = Blogentry.find_all_by_category_id(@category.id)
    elsif (params[:month] && params[:year] )
      start = Time.mktime(params[:year], params[:month])
      @blogentries = Blogentry.find(:all, :conditions =>
[''created_at
> ? and created_at < ?'', start, start.next_month])
    else
      @blogentries = Blogentry.find(:all)
    end
  end

//blog.html.erb
<% for blogentry in @blogentries %>
<div id="blog_entry">
	<div id="blog_heading">
		<%= h blogentry.title %>
	</div>
	<div id="blog_content">
		<%=h blogentry.body %>
	</div>
</div>
<% end %>

//layout.html.erb (only the sidebar code with Archives and
Categories).
//This file provides the category, month and year required for
categorizing and archiving //respectively.

<div id="sidebar">
	<div class = "side_content">
	<div> CATEGORIES </div>
	<% for category in @categories%>
		<% @entry = Blogentry.findforCatergoryid(category.id) %>
		<%= link_to category.name.upcase + "(#{@entry.length})",
category_entries_path(category.name)%>
		<% end%>
	</div>
	<div class = "side_content">
	<div> ARCHIVES </div>
	<% @entries_by_month.each do |month, entry|%>
		<%= link_to month.strftime(''%B %Y'').upcase, 		  
archive_path
(month.strftime(''%Y''),
month.strftime(''%m''))%>
	<% end%>
	</div>
</div>

Any help here will be be greatly appreciated.

Thanks,
vishy

to answer your first question, hiding the comments by default is easy.
simply add a "display:none" to the CSS for the divs you wish to be
hidden initially.
