I notice that the BMP085 runs from 3.3V, so you will need to use a 3.3V supply and disable the weak pullups to 5V in the Arduino wire library (see comments on product page) You can probably run the other sensor from 3.3V too but you would need to confirm this - it should work fine from 5V with logic high to 3.3V anyway if necessary.

A powerful but easy to use BMP085/BMP180 Library

Using the sensor is easy. If you're using an Arduino, simply connect the VIN pin to the 5V voltage pin, GND to ground, SCL to I2C Clock (Analog 5) and SDA to I2C Data (Analog 4). Download the BMP180 Arduino library and example code for temperature, pressure and altitude calculation.
