Working 9to5 I hope you find a place that is right for you. The above posters have all said (much better than I) lots of fab things about Baptist churches.
I go to a small free church which is very similar to a Baptist Church, we do not have our own building but do have a paid minister and an elder or two.
I started going to a free church four years ago because we moved from a large Anglican one and I must admit I miss some of the stuff (like communion) although having gone to an evangelical (low) Anglican church there was not much 'pomp' if you know what I mean!
The things I noticed most are that we have church members meetings where we all hear about everything! which is very different from C of E where a committee (PCC) decides stuff.
The communion in our church is pieces of Matzo bread and tiny plastic cups of wine (grape juice). When we have communion we eat the bread when we receive it individually and then all drink our tiny cups together! All churches may vary so maybe if you take communion just watch what ones do! 
One big difference will possibly be whether or not the Baptist church is a member of BUGB www.baptist.org.uk/ if they are then you can take a look at the BUGB website and see more about them. If they are not then see if they are affliliated to any other organisation. For example a Baptist church near us is a member of the Fellowship of Independent Evangelical Churches FIEC and my church is also a member of the FIEC. Members of the FIEC do not accept women in main leadership roles, so they would not have women elders or pastors but they would have women leading worship, reading the Bible, leading Sunday school, helping with outreach and leading in smaller groups like house group and maybe an evening service.
Personally, I do not agree with the limitation of women in leadership
but we choose our church by heart not head, as in we went along and loved the people
before I found out that women do not have ultimate leadership roles!
In some ways this is probably similar to the current situation with the C of E, not having women bishops (although I think that will change) and of course the Roman Catholic Church not having women priests.
I wanted to say this because I was probably under the impression that Baptist churches all accepted women leaders and if you go to a service you may well see a woman up the front doing things at church and assume they can do anything! So if you want to know what they believe or think, then ask, don't assume it will be the same as you are used to or the same as other churches, unlike Roman Catholic or Anglican churches, Baptist churches have more freedom to vary exactly how they run things, I think!
It really depends what is important to you and so it is worth checking out the individual church website should somewhere state what they believe and which organisation/s (if any) they are affiliated to.
The adult baptism thing is something I am more than happy with and we chose not to have our daughter baptised as a child (she was dedicated in an Anglican church). When we arrived at our free church we attended for a year and then became members, which involved being formally welcomed in the service. We were not asked to be baptised as adults and the fact we had made our own declaration of faith as adults in our own C of E context many years ago was fine. I actually think I would be happy either way but again you may wish to just ask what they think if you find yourself wanting to actually join.
Good luck and please do let us know how you get on.
