Using a 2-gang box, can I install a (1) outlet, (2) coax, and (3) Cat-6 line without code or interference issues?
I have an existing 1-gang box with electrical that I am running the coax and cat-6 towards. The new lines don't follow the electrical line, but I am unsure if having all the outlets so close may also cause interference or code issues.
Is it okay to put them all in the same box?
I like power strips similar to this for work areas. They are nice because they have an on/off switch, which if mounted in an easy to reach location could save life and limb.
Using a power strip like this should not be a problem, as long as you don't run too many tools at once. And it should conform to most codes, as it would be classified as an extension cord (I think).
Since you are in a one-family dwelling, there is really only one important article to be aware of.
800.26 Spread of Fire or Products of Combustion. Installations of communications cables and communications raceways in hollow spaces, vertical shafts, and ventilation or air-handling ducts shall be made so that the possible spread of fire or products of combustion will not be substantially increased. Openings around penetrations of communications cables and communications raceways through fire-resistant-rated walls, partitions, floors, or ceilings shall be firestopped using approved methods to maintain the fire resistance rating.
FPN: Directories of electrical construction materials published by qualified testing laboratories contain many listing installation restrictions necessary to maintain the fireresistive rating of assemblies where penetrations or openings are made. Building codes also contain restrictions on membrane penetrations on opposite sides of a fire resistance–rated wall assembly. An example is the 600 mm (24 in.) minimum horizontal separation that usually applies between boxes installed on opposite sides of the wall. Assistance in complying with 800.26 can be found in building codes, fire resistance directories, and product listings.
In a one- or two-family dwelling, you can use general type cable (CM, CMG, CMX) anywhere other than where plenum cable is required.
800.154(B)(3) One- and Two-Family Dwellings. Type CM and CMX cable shall be permitted in one- and two-family dwellings.
Or, under carpets.
800.154(C)(6) Under Carpets. Type CMUC undercarpet communications wires and cables shall be permitted to be installed under carpet.

Yes you can, as long as you keep the conductors separated. However, you should likely avoid it if possible. Common practice is to keep power and communications circuits in separate stud bays.
National Electrical Code allows you to put power and communication circuits in the same box, as long as all the conductors are separated by a permanent barrier or listed device.
Here's an example of a listed device:
