Well, standard 2.3.4 is the official current release, although it's unsupported and won't run on PHP versions past 5.3 or maybe 5.4. Your host probably installed it because they found it as the "official" release, but you should not be using it. When your host upgrades PHP to 5.5 or higher, your store won't work. If you're just starting on a new version, you should be running osC 2.3.4BS Edge (community supported). It runs on PHP 5.6 (soon to support 7.0), and is responsive. Any chance of your starting over with 2.3.4BS? You should be able to migrate your data over and not lose any of it, although any custom features from the template you were using will be a problem. Does telus offer templates tailored for 2.3.4BS? What exactly do you mean by getting a "template" from them? The word means different things to different people. Is it a customized version of osC provided by your host? That could mean anything from minor CSS tweaks to massive amounts of new code. Is it created by your host (probably not that far from stock) or by a third party? Third party "templates" are often heavily modified versions of osC, while most hosts would not have the resources or expertise to get that deeply into it.
