What happens if you keep shaking a water bottle?

Viscous deformation of the water causes its internal energy and temperature to increase. The answer to your second question is that it will start to warm ever so slightly as soon as you start shaking it.

Let us assume you shake from each side at a rate $f$ of say four times per second attaining $Delta v/2=5 mathrm{mph}$ $simeq$ 8 kph before reversing directions, and that some fraction of the energy $eta$ you give each switch is converted into heat which is absorbed by the water, and that none of it is radiated out. The value of $eta$ will change based on how full the bottle is. If the bottle is 100% full, then there will be no internal motions for viscosity to convert the energy into heat, and $etasimeq0$. To understand this situation (the $etasimeq0$ full-bottle case), one could "heat" the water by putting the bottle into a simple harmonic oscillator (with a spring), and it would go back and forth without heating the water and without any expenditure of energy. By conservation of energy, no heat can be added to the water.

Continuing, the desired change in energy is

$$Delta E=M_ ext{water}C_VDelta T,$$

where $M_ ext{water}$ is the mass of the water, $C_V$ is the heat capacity of water, and $T$ is the temperature, with $Delta$ denoting changes.

Meanwhile, the total heat supplied will be

$$Delta E=N eta {1 over 2}M_ ext{water}{Delta v}^2,$$

where $N$ is the number of single-direction shakes.

Solving for $N$, we get

$$N={2C_VDelta T over {eta Delta v}^2}.$$

The total time it takes will be

$$T={Nover f}={2C_VDelta T over eta f{Delta v}^2}.$$

If warm is $100 mathrm{^circ F}simeq38 mathrm{^circ C}$ and cold is $32 mathrm{^circ F}=0mathrm{^circ C} $, $Delta Tsimeq68 mathrm{^circ F}simeq38 mathrm{^circ C}$. 5 mph $simeq$ 2.2 m/s. So, if $eta=0.5$, $$T={2 imes 4184 mathrm{frac{J}{kg K}} 38 mathrm K over 0.5 imes 4 mathrm s^{-1} imes left(2 imes2.2 mathrm{mover s} ight)^2}=8212 m space secondssimeq 2 space hours space 16 space minutes.$$ This doesn't account for radiative losses during that time, although that won't become too important unless you want to make tea. Actually, if you wanted boiling hot water for that purpose, then you could have made such tea in a few minutes of shaking (without changing the temperature much) because the motion will drastically increase the effective diffusion rate of liquid through the tea leaves vs. stagnant water. I'd like to thank Loong for syntax corrections and also Ujjwal Barman for asking a question that made me want to include a $eta$ factor, as the original answer had none and I'd hate to have someone shake a full bottle for hours only to find disappointment!
