You can move to BLW anytime. I would highly recommend reading the BLW book by Gill Rapely. It will give you (and your DH) a better understanding of why BLW is beneficial and the basic principles - which is basically leaving the baby to feed themselves and trusting that they will eat what they need (that's hard for some parents to do).
But it's easy (the lazy way to wean) as baby eats whatever you eat as long a you eat a healthy diet and being mindful of salt content.
There are only two things to avoid: honey before 1 years old and whole nuts (due to choking). If there are allergies in your family, slowly introduce foods such as eggs, berries to see if there is a reaction - otherwise cook a dinner and put some in front of dd and see what happens! mess, more mess and lots of fun! 
BLW does get confused with giving finger foods alongside purées as purees/ spoonfeeding is parent led not baby led. You need to consider if you want to stop purées altogether or begin offering food that you're eating each meal time alongside purée and then perhaps slowly phasing purée out which would mean going down the BLW route.
Given that you dd has only been on purée for a couple of weeks, i imagine she isn't on a lot, so you could easily phase it out. You'd be surprised how quickly they pick up new coordination skills eating.
If she isn't quite sitting up, I would be very cautious and watch her carefully when giving her food. Have a look on YouTube for gagging videos. Gagging isn't choking but can be confused.
As for BF'ing - even if you stuck with purée you can still bf for as long as you want. Haven't heard that before.
You need to get your DH on board with the choice to wean. If he has put pressure on you to wean earlier than you wanted then he may not be 'with you' about BLW - it is a scary concept for some. That book really helped - I just read snippets out to DP. He said to me yday (dd is now 10 months and we did BLW from 6 months) that I should be proud of the choice I made. I told him "we" made the choice to BLW but he said I did the research and gave him the info and I've been at home with dd and followed it through. It was a nice compliment as he wasn't so keen at first.
There is a good BLW Facebook group: Baby led weaning - let your baby feed themselves with loads of tips and ideas.
Good luck.
