Can someone point me in the right direction. I am looking to develop an application for a Verizon enV Touch, but I am totally clueless when it comes to this. Any advise on the technology used, the development tools needed, or application programming for cell phones in general is greatly appreciated. I basically need "Cell Phone Application Programming for Dummies"

Dashes (-) have no significance other than making the number more readable, so you might as well include them.
Since we never know where our website visitors are coming from, we need to make phone numbers callable from anywhere in the world. For this reason the + sign is always necessary. The + sign is automatically converted by your mobile carrier to your international dialing prefix, also known as "exit code". This code varies by region, country, and sometimes a single country can use multiple codes, depending on the carrier. Fortunately, when it is a local call, dialing it with the international format will still work.
Using your example number, when calling from China, people would need to dial:
00-1-555-555-1212
And from Russia, they would dial
810-1-555-555-1212
The + sign solves this issue by allowing you to omit the international dialing prefix.
After the international dialing prefix comes the country code(pdf), followed by the geographic code (area code), finally the local phone number.
Therefore either of the last two of your examples would work, but my recommendation is to use this format for readability:
<a href="tel:+1-555-555-1212">+1-555-555-1212</a>
Note: For numbers that contain a trunk prefix different from the country code (e.g. if you write it locally with brackets around a 0), you need to omit it because the number must be in international format.
[#1] Smart Watch
To fetch heart rate data from sensor you have to develop a Tizen UI/service application. In that Tizen application, you have fetch data using Sensor/Human Activity Monitor API. You can chose either Tizen Native API for Native app (C/C++) or Tizen Web API for Web app (HTML/CSS/JS).
Guides:

or Native API

[#2] Smart Watch to My Cell Phone
For connection and data transfer between mobile android device and Samsung Gear device , Accessory Protocol is defined. So, the option available here is using Accessory SDK for Android mobile and Tizen wearable.
You may check my response on similar issue on this post, the difference is just 'step count' instead 'heart rate'

Obviously bluetooth won't be a solution for this case, you may check the documentations on Web socket on the post above. You may think of HTTP request-response also.

There is no "Dummmy" or general book. Cell phones vary in countless ways - cpu, software, etc. Does the enV have official "app store" and SDK? That would make it much easier.
My hunch is that this phone uses Java like a lot of phones do, but I can't be certain. But even then, the libraries will vary based on manufacture and carrier. If there is no store, you will have to work through Verizon or LG to get the tools needed.
One possibility is to use Flash Lite, which is enabled on this phone.
