Yes, your filtration can definitely affect your stocking levels, although in a 10g there won't be too much of a difference between reccomended filters. My favorite HOB (Hang on Back filter) is the Aqueon 10, it's easy to set-up (pretty much just plug it in), it can handle up to a 20g tank, and it's filter cartridges come pre-assembled.
Here is my personal favorite site for stocking, aqadvisor.com
It's a great site, although it's not perfect. I ussually use it to get an idea of what will work, and then I run it by the forum to see their thoughts.
Good luck!
