You're welcome, glad we could help out! Although I believe it's Druids who summon natural allies in 4e. But Rangers have an option to have an animal companion if that's what you're looking for.
Also worth looking at if you're concerned with being effective in combat is the well known and well respected Shoot To Thrill ranger build. Here's a link to that build
if you want to check it out. Be aware that this build assumes you take Archery style, and not an animal companion. It's also very optimized, probably more optimized than most of us would ever need for casual play, so deviating from the build to conform closer to your concept likely won't slow you down much.
