Well, what kind of tone are you going after?
Consider trying a Sennheiser E906 and/or md421 especially together with the SM57, those are the most typical and usual suspects. There is no shortage of fantastic sounding recordings made with a 57, mind you. The pr30 is pretty sweet too. As are other mics. Rule of thumb though, if you cannot get one mic sounding good then two might just make matters worse for you... and open up a whole new box of issues. Pick one mic, two if you really have to and can get phase sorted out. Then experiment with those on your speakers, especially since you have k100s and v30s. Positioning and picking the right speaker is key. And picking the right mic for it, too.
I go to a pro studio I'm not an engineer
The whole prostudio literally means nothing if you don't really know what you are doing there, please don't be offended by this, you said it yourself, you are no engineer. The way I see it, you have two options: you can definitely get a solid recording with one sm57 or one e906 and even a cheap focusrite interface would do, or apogee if you really want to or any other interface for that matter. From there, it's all about mic position, recording multiple takes and layering stuff and then making it shine in the mix. What you record always tends to sound a little "raw", even more so with the 57 and v30s - then in editing and mixing you give it that special shine and that's a whole other set of skills. (editing and mixing)
The other option you might want to consider, since you already do have access to a great studio for which you are paying, I assume, well you might as well save yourself all that trouble and time and rent a local tech to get you hooked up and tracking. If he knows his shit and the studio and gear, he should easily be able to capture better results than you on your own. The thing about all that "magical" analog gear is, you got to know exactly what it does and what characteristics it has to be able to really make it work FOR you and not against you.
I know people love to have shiny gear but the simple truth is, if you cannot get a decent sound with a simple homerecording setup à la apogee and a 57/e906/421, then the same steps are going to sound crappy through the boutique-st of the boutique outboard gear. Analog recording gear is more about juggling several characteristics and often gear-oddities together to create a strange voodoo mixture that works surprisingly well... and that can be amazing if you know exactly what you are doing and how to gain stage and combine! But for simple DIY recording, I am going to go ahead and say you are better off in the digital realm with just a decent mic and a good quality interface and then just work that setup until it sounds good. Every speaker and every mic are going to have some upsides and some things you will be struggling with, so don't start looking for that one magic silver bullet that will just do it all, if only you know how to find it... stick with what you got and do everything you can do make it sound as good as it can.
