I question the wisdom of a 410 for your needs. You are only going to mic one speaker- micing more is just a silly waste of microphones and tracking channels.
I see the reason to go direct, but you will limit yourself to a, well, direct sound, if you have no cab to resource.
a 5-watter is a small-studio staple, but you won't get a wide range of tones or sounds from it.
So, starting with your listed needs, here are my suggestions, drawn from my own, similar needs and setup. Thoughtful guy I am, I am even including a grain of salt, for you to take with them.
GUITAR AMP: 20 watts or less, with wide palet of tones and effects. I have been happy with a Fender Super Champ XD- it has tube power amp, emulates several vintage amps (I know from direct, A/B comparision, that the Acoustosonic, Fender Champ and Fender Deluxe Reverb are all nearly spot-on, and the Marshall high-gain voice is darn close,) and has several on-board effects, with a level control for any of them. Only real drawbacks I have seen are inability to use some effects with others (can't use tremolo and reverb together, which is a particularly odd failing,) and the stock 10" speaker is somewhat lacking in bass response. Fix the first with a pedal or two, the second with a replacement speaker. I put an Eminence Ragin' Cajun in my SCXD, although I was a bit dissapointed with the results- not sure it was a cost-effective mod.
BASS AMP: Something around 40 to 50 watts. Bass takes more wattage to compete with a guitar amp, and solid-state watts are not as "loud" as tube watts (I don't know the science behind that, but in a real-world situation, it is pretty universally true.) My current way-budget bass amp is an older Peavey Basic 40. Previously was a 25-watt Fender bass amp (I think they sell it as a Rumble 25 now, or something) and it worked well for my little home studio. When I can find one that I can afford, I'm snagging a SWR 10" or 12" bass amp.
I'd make sure both amps have a speaker-out plug, so you can use an attenuator on the power-amp tubes, and/or plug either amp into a fully-enclosed-speaker cab, which has a speaker in it, but is completly sealed so that little sound escapes. Either of those schemes will allow you to drive the amp hard without making a lot of noise that will disturb family or neighbors, or shake the building's foundation. (Rattling windows and yellings of "TURN THAT S*%T DOWN!" are SO hard to EQ out of a mix...)
Advantages:
Small size- takes up little closet space.
Low power.
Means of attenuating output, to control volume yet get hard-driven tone.
Lots of different tones and sounds, so that you can get "there," or at least very close, to almost any amp's tone.
With 20 watts (guitar) and 40-50 watts (bass) if someone wants to play out or jam with either amp, you have a reasonable chance of having enough power for that use (I know this from experience, not specualtion.)
Disadvanteges:
Having to convince the guy who you talked into leaving his Marshall double stack at home that your rig will sound just like his.
COST:
SCXD- about $200-250, used.
40-50 watt bass amp: $50 to $200 used.
25-watt attenuator: $200 new (hard to find used, but $50 to $100 if you can.)
Enclosed speaker boxes: I would guess about $100 each, if you build them yourself.
Replacement speakers: Ragin Cajun- about $60, bass speaker about the same.
So, for $400 to about $800, you are done. Does that fit in your budget?
Oh, and as promised...
