Adding features to mybloggie

I recently had a second blog installed on my website, mybloggie. It works great. Now I'd like to add the following 10 things to it: 1) Limit the number of posts that appear on the main page (right column) to 3-4. Right now they keep scrolling down with no cutoff. Need this fixed ASAP 2) Need a date stamp included with each post (just the date, not the time) 3) Need to set up a hidden login page for blog contributors. There was a login set up for them, but it was on the main blog page where anyone could try to login or set up an account. 4) Need the ability for contributors to go back and edit their posts 5) Need to give contributors administrator rights 6) Need to add the ability to archive posts to 25 per page. 7) Need a back button added to posts 8) Hyperlinks in posts aren't working (I can go in and manually fix them in mysql) 9) Need to add my website stats code to the blog page (and posts if possible) 10) Finally, unless this is way too much work beyond the scope of the project, upgrade the text editing box to permit more functions I encourage Rajneesh & Master Solution to bid again, since they both did such a great job for me before.
