I wouldn't bother with Telnames, little use to you (or many people). Neither will any separate mobile domain be a great idea in your case, you then have two websites to maintain, optimise, promote. There are businesses where another site (or subdomain) makes sense but not so many. The whole idea of a separate mobile web may have seemed logical for a while but in general will not happen.
Also worth noting that in the longer term, none of this will be needed. I was fortunate recently to see a couple of still primitive but fascinating "thin air" screens projected from mobiles. A long way to go and battery power is an issue but they are the future. Staring at a few inches of gorilla glass may have seemed interesting but never a solution.
A good way off though and your site could be "mobilised" with media queries, worth bearing in mind that creating a responsive option can mean leaving a few aspects out on smaller screens. As you are using Wordpress, why not just switch to a responsive template. There are literally thousands around, you can see a few on this advertorial site:
Probably no need to pay if you hunt around. There are also plenty of ways to incorporate Bootstrap, or a template based on this:
An interesting project, particularly for those liking off the peg modules. Can be best used with a fair bit of stripping out, depends on your intentions. Still feel your best bet may be spending a while hunting for a ready made template, even if you need to make minor modifications.
Minor point on your site, worth having a good read on canonicalisation for wordpress. I see you are using Joost De Valk's plugin. which I'm not so familiar with but may need tweaking. As an example, this snippet/tag page:
is indexed and canonicalised to itself. The tag should instead point to the main page the extract belongs to, which I imagine is:
There may also be other URL variations available for indexing. If possible, one indexable URL for each piece of content is good.
