Efficiently query table with conditions including array column in PostgreSQL

Need to come up with a way to efficiently execute a query with and array and integer columns in the WHERE clause, ordered by a timestamp column. Using PostgreSQL 9.2.

The query we need to execute is:

SELECT id 
from table 
where integer = <int_value> 
  and <text_value> = any (array_col) 
order by timestamp 
limit 1;

int_value is an integer value, and text_value is a 1 - 3 letter text value.

The table structure is like this:

    Column     |            Type             |       Modifiers
---------------+-----------------------------+------------------------
 id            | text                        | not null
 timestamp     | timestamp without time zone |
 array_col     | text[]                      |
 integer       | integer                     |

How should I design indexes / modify the query to make it as efficient as possible?

Thanks so much! Let me know if more information is needed and I'll update ASAP.
