Based upon what you wrote, you should create an account at visa4uk and use it to apply for a 'Standard Visitor Visa'. Your husband does not qualify as a family sponsor, so you would fill out the form like in this image...
Should i book tickets before the visa will that make any difference on the decision?
It is a very bad idea to purchase tickets in advance of a visa application. It tells the decision-maker that you did not read the guidance and probably do not understand the rules. You also undergo the risk of cancelling tickets in the event your application is not successful or it takes a long time for them to reach a decision.
Here's a screen shot of the relevant guidance...
And finally, in the remarks section of the form, you put down that you are visiting your husband and include his entry clearance number. If you have problems substantiating your marriage, then use 'partner' everywhere. Your husband/'partner' should write a letter to the consulate supporting your visit (naming you as wife or partner) and you should include it with your application. They prefer wet signatures if possible. It's ok to explain in the remarks section why you do not have a license as long as the explanation is reasonable.
