Bangkok is a great place to live. The only downside to expat life is that you lose friends as they move back home or to other countries.
My children where too young for school when we lived in BKK and I found this organisation really useful. It could still be a good way for you to meet people (and find a maid). This is where I found out about Mumsnet and my life hasn't been the same since! www.bambiweb.org/
My knowledge is out of date I left in 2003, but if I was going out for a go and see trip with children I would stay in a serviced apartment rather than a hotel. Expats also live at these locations so you will get to meet people around the pool.

This place is on top of a ritzy shopping centre, next door to a park and with a train station. www.emporiumsuites.com/index.html (I lived within walking distance of here.)
Lots of time can be lost in commuting. I would find out where your husband will be working and see if there are schools and other services that suit you in that area.
When I lived in BKK, Patana was very popular but it seemed a long way out to me. Children were doing very early morning commutes in the school bus, or people lived close to the school in sort of enclaves. Neither appealed to me and I would have been happy to send my children to a school closer to were we lived.
However, if your husband is working in a 'remote' part of BKK you may prefer to have a supportive community around you.
Living close to a Skytrain station is a good idea. The traffic and flooding can sometimes leave you stranded. I have been told that the metro stations are in strange places, but that is just heresay.
