I'll do my best, but I am just an egg compared to many on the board, hopefully you will get others chiming in as well.
The two mic are of different kinds (check out the stickied posts in the microphone forum, it will tell you everything. In the end of the first one someone posted a link to a page that condenses everyhting-- including some "standards" for choices in entry level and other prioce, very helpful!).
I've never used either, but i can toss out conjecture with the best of them:
The PG58 is a dynamic that appears to be a bit more affordable model of the SM58 (which i have one of), also by shure. The SM58 is a standard dynamic, probabaly best used for vocals, my acoustic guitar tracks recorded on it suck anyway. It might also hold up for micing amps, or some drum micing here and there. It is probably a good bit more sturdy than the MXL 990 and better suited to live applications.
The 990 is a large diaphram condensor, which will require phantom power (the behringer mixer has this, so you are set there) and will give a very different tone and quality. As a rule, the LDC are used from a bit further distance and pick up sound much more sensitively (like the fridge runnning downstairs). These tend to excell with instrument recording, and can give good color to vocals (as mentioned they are very sensitive so may let throguh some unpleasantness if the source has it as well). In a good room, LDCs can add quite a bit to your recording.
I'd be wrong to make any kind of reccomendation, i just don't have the experience, but if you read the mic threads i mentioned you will hear a great deal from some of the best.
Eventually having more than one mic for different situations is a goal to shoot for, and the rule is generally buy the best thing you can afford. You could probabaly find an SM57 or SM58 used for about the same price you mention above, which would probably be preferrable to the PG58, and for $30-40 more you could open your options on the condensor mics up to many of the ~$100 ones that people speak highly of as well.
As for cabling, you will need to get some XLR cables, one for each mic you might be using, and the same rule applies, you tend to get what you pay for. Monster cables are warrenteed for life I think, and some cheap ones might add noise to your signal or go bad quickly.
Hope this helps,
Daav.
