About the Deities, installation is another thing. You should not install Them because if you do that then you are obliged to a certain standard and timings.
But I am sure you didn’t mean that.
There are many details, like cleanliness of the altar and of your person when you offer something. We can talk more when I come back.
For the time being you take a sankalpa, which is a pledge of a minimum offering, which can be increased in the future.
Keep it very simple because if you can do more is good but if you can’t it’s not good at all. Like for instance pledge everyday an incense and a cup of water and change their clothing once a week. Something like that.
Of course you should offer bhoga on the altar so that becomes prasadam. My picture should be smaller that Srila Prabhupada’s murti and that should be on the right side of him.
If you go traveling you can do the offerings in meditation.
Your well-wisher
