Answer 1

Assuming you are using version 1.5.2.RELEASE of spring-data-mongodb (as I remember from a previous question of yours) and the credentials are stored in the admin database these should be your MongoDB related beans settings:
<bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean">
<property name="host" value="54.172.243.152" />
<property name="port" value="27005" />
</bean>
<bean id="mongoCredentials" class="org.springframework.data.authentication.UserCredentials">
<constructor-arg name="username" value="smynapati" />
<constructor-arg name="password" value="smynapati" />
</bean>
These stay intact. Next come:
<bean id="mongoDbFactory" class="org.springframework.data.mongodb.core.SimpleMongoDbFactory">
<constructor-arg name="mongo" ref="mongo" />
<constructor-arg name="databaseName" value="test1" />
<constructor-arg name="credentials" ref="mongoCredentials" />
<constructor-arg name="authenticationDatabaseName" value="admin" />
</bean>
Finally comes the template:
<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
</bean>
Note that you'd better use the mongo XML namespace for simplicity.
